+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future

+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>

+Installation Instructions
+*************************
+
+Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005,
+2006, 2007 Free Software Foundation, Inc.
+
+This file is free documentation; the Free Software Foundation gives
+unlimited permission to copy, distribute and modify it.
+
+Basic Installation
+==================
+
+Briefly, the shell commands `./configure; make; make install' should
+configure, build, and install this package.  The following
+more-detailed instructions are generic; see the `README' file for
+instructions specific to this package.
+
+   The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions.  Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+   It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring.  Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.
+
+   If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release.  If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+   The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'.  You need `configure.ac' if
+you want to change it or regenerate `configure' using a newer version
+of `autoconf'.
+
+The simplest way to compile this package is:
+
+  1. `cd' to the directory containing the package's source code and type
+     `./configure' to configure the package for your system.
+
+     Running `configure' might take a while.  While running, it prints
+     some messages telling which features it is checking for.
+
+  2. Type `make' to compile the package.
+
+  3. Optionally, type `make check' to run any self-tests that come with
+     the package.
+
+  4. Type `make install' to install the programs and any data files and
+     documentation.
+
+  5. You can remove the program binaries and object files from the
+     source code directory by typing `make clean'.  To also remove the
+     files that `configure' created (so you can compile the package for
+     a different kind of computer), type `make distclean'.  There is
+     also a `make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+  6. Often, you can also type `make uninstall' to remove the installed
+     files again.
+
+Compilers and Options
+=====================
+
+Some systems require unusual options for compilation or linking that the
+`configure' script does not know about.  Run `./configure --help' for
+details on some of the pertinent environment variables.
+
+   You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment.  Here
+is an example:
+
+     ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+   *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you can use GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+   With a non-GNU `make', it is safer to compile the package for one
+architecture at a time in the source code directory.  After you have
+installed the package for one architecture, use `make distclean' before
+reconfiguring for another architecture.
+
+Installation Names
+==================
+
+By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc.  You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX'.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files.  Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System).  The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+There may be some features `configure' cannot figure out automatically,
+but needs to determine by the type of machine the package will run on.
+Usually, assuming the package is built to be run on the _same_
+architectures, `configure' can figure that out, but if it prints a
+message saying it cannot guess the machine type, give it the
+`--build=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+     CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+     OS KERNEL-OS
+
+   See the file `config.sub' for the possible values of each field.  If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+   If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+   If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+If you want to set default values for `configure' scripts to share, you
+can create a site shell script called `config.site' that gives default
+values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+Variables not defined in a site shell script can be set in the
+environment passed to `configure'.  However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost.  In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'.  For example:
+
+     ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for `CONFIG_SHELL' due to
+an Autoconf bug.  Until the bug is fixed you can use this workaround:
+
+     CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+`configure' Invocation
+======================
+
+`configure' recognizes the following options to control how it operates.
+
+`--help'
+`-h'
+     Print a summary of the options to `configure', and exit.
+
+`--version'
+`-V'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`--cache-file=FILE'
+     Enable the cache: use and save the results of the tests in FILE,
+     traditionally `config.cache'.  FILE defaults to `/dev/null' to
+     disable caching.
+
+`--config-cache'
+`-C'
+     Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to `/dev/null' (any error
+     messages will still be shown).
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`configure' also accepts some other, not widely useful, options.  Run
+`configure --help' for more details.

+NEWS
+====
+
+--------------------
+0.6.10 (2009-10-25)
+--------------------
+ * Bug Fixes:
+   - fixed installation bug which caused manpages to be installed in /man;
+   - fixed mode of installation to support sandbox-builds on Gentoo (Lovelace);
+   - improved (automated) linking process, now possible to pass LDFLAGS (Boeck);
+   - bail out when no statistics are available, instead of flagging an error.
+
+--------------------
+0.6.7 (2009-07-09)
+--------------------
+ * Screen geometry:
+   Reduced the screen size again, to 24x80, since this is a widely used default
+   size (thanks to Nelson A. de Oliveira). Removed the "wireless extensions"
+   information from the information screen, to reduce the minimum required
+   number of lines from 25 to 24. The wireless extension information however
+   remains still available, via the "wavemon -d" dump option.
+
+ * Histogram screen improvements:
+   - a new revised approach to fix several old bugs and limitations,
+   - new code better observes the boundaries and the configured ranges,
+   - better visibility, signal/noise are now plotted in bold.
+
+ * Better separation of error messages, into:
+   - informational warning messages (outside ncurses mode),
+   - fatal errors unrelated to system calls,
+   - fatal errors following a system call (with interpretation of errno(3)).
+
+ * Bug Fixes:
+   - fixed a bug in the histogram initialisation (producing ghost values);
+   - fixed a bug which caused non-ASCII encryption key strings to be garbled;
+   - key string length is now checked to avoid spilling over the right border
+     into the next line; curtailing long keys in a pretty-printing manner.
+
+--------------------
+0.6.6 (2009-06-01)
+--------------------
+ * Access point screen:
+   Overly long access point lists (more than 6 peer access points) are now
+   truncated, so as not to overwrite screen borders.
+
+ * Histogram screen:
+   The bottom 'key' window used to replicate the configured range values which
+   are available also via the configuration screen. This replication has now
+   been superseded by a dynamic range-tracking feature:
+   - for each of the three ranges (signal level, noise level, SNR), it shows
+     the min..max values on the screen or 'unknown' if the driver reports
+     values as unknown (e.g. noise levels on iwl3945),
+   - these values correspond to the current histogram and are updated
+     dynamically, thus complementing the visual display.
+
+ * Bug Fixes:
+   - histogram screen no longer tracks values that the driver reports as invalid;
+   - fixed off-by-one bug which caused the bottom access-point border to be erased;
+   - miscellaneous code clean-ups:
+     o unified description of window sizes via header file constants,
+     o updated and extended source code documentation.
+
+--------------------
+0.6.5 (2009-05-08)
+--------------------
+ * Several improvements in displaying driver parameters:
+   - ESSID: support for indexed ESS identifiers,
+   - nickname: no longer present empty/void nicknames,
+   - nwid: added support for displaying it (even if is pre-802.11),
+   - IP-address: collapse netmask information into shorter CIDR prefix length,
+   - mode: preliminary support to display 802.11s mesh mode (2.6.26),
+   - retry: new code to display information about MAC-layer retransmissions,
+   - frequency: suppress trailing zeroes, unified conversion,
+   - channel: now also prints the number of the current channel,
+   - encryption keys: added pretty-printing, suppress always-present '0' index,
+   - sensitivity: only print if card supports it, now also supports dBm values,
+   - tx-power: better support for the various formats (relative | mW | dBm),
+   - power management: improved output formatting.
+
+ * Mode-sensitive display:
+   - when operating in 'monitor' or 'access point' mode, the 'access point'
+     field is not necessary or redundant (in AP mode, it is the same as the
+     mac address shown in the network window), hence omitted;
+   - when operating in 'master', 'repeater' or 'secondary' mode, the bitrate
+     information is also not needed and hence suppressed;
+   - wavemon is now able to distinguish auto-configured values (using upper-case
+     labels) from manually configured values (using standard lower-case labels).
+
+ * Encryption keys (only with CAP_NET_ADMIN privileges): display of all-ASCII
+   keys is now in cleartext, otherwise the hex format is now pretty-printed.
+
+ * Screen Layout: redundancies (repeated interface name) have been removed, the
+   whole screen fits again into a 25x80 console window. In addition, wavemon
+   tests if the screen size and bails out if the screen is too small for a
+   readable layout.
+
+ * Better display of MAC addresses:
+   - detects the "not associated" state of a managed client and then
+   - displays 'non-associated' state instead of showing zero MAC address,
+   - sanity checks on access point addresses (broadcast address is invalid),
+   - Ethernet addresses are automatically translated to symbolic names if a
+     mapping  exists for the MAC address in /etc/ethers.
+
+ * The Access Point List is now sorted in descending order of signal strength.
+
+ * The LC_NUMERIC locale is honoured: when displaying large numbers (e.g. packet
+   counters, numbers are now grouped according to the locale.
+
+ * Bug Fixes:
+   - fixed several conditions which caused the window borders to be punctured;
+   - fixed a bug in the display of MAC addresses on the access point screen;
+   - RTS/CTS threshold suffered from the same problem - also fixed,
+   - fixed broken display of frag[mentation] threshold;
+   - fixed a bug which caused empty nicknames ("") to be displayed;
+   - fixed several smaller bugs, thanks to sparse.
+
+--------------------
+0.6 (2009-04-01)
+--------------------
+ * Update to the latest wireless extension API (number 22),
+   As a consequence of updating the wireless extensions, more
+   information is now displayed, including
+   - excessive TX MAC reassembly retries,
+   - missed beacon count
+   - display of wireless extension version used by the driver
+   - the driver's internal WE version
+
+ * wavemon now uses ioctl to obtain IW statistics and falls back
+   to /proc/net/wireless only as a last resort. (It is planned
+   to add netlink support in a later release.)
+
+ * Linear scales (-l option) no longer supported, since levels
+   are always reported both in log (dBm) and lin (mW).
+   (NB: in case of using an old version of ~/.wavemonrc, it is
+        necessary to remove the line containing 'linear_scale',
+	which is the option that has been removed.)
+
+ * Added sanity checks to the display of level information:
+   - noise level is only displayed if valid signal levels exist;
+   - some cards set a magic number to mean an invalid noise level - a
+     constant has been added to catch such cases;
+   - if the noise level (and hence the SNR value) is undefined, spread
+     out the  display of quality/signal levels over the info window.
+
+ * Added gui option for smoothing level meters (better readability).
+
+ * Much better and more accurate information in the Access Point List.
+
+ * Bug Fixes:
+   - it is finally possible to use the Access Point List as start screen,
+   - updated and fixed display of operation modes,
+   - selecting the wireless interface now works with multiple interfaces,
+   - header inclusion bug fix for Puppy Linux (thanks to Tom Gordon).
+
+ * Updated all components of the autoconf build system:
+   - DESTDIR is now supported for building packages
+     (thanks to Christoph J. Thompson),
+   - now using autoconf to set package version and build date.
+
+ * Reorganised source tree organisation:
+   - merged many small (one-line) header files into one,
+   - created a 'contrib' directory for contributed scripts,
+   - added 'config' directory for autoconf auxiliary scripts
+   - reinstated standard GNU autoconf listing of files
+
+--------------------
+0.5 (2009-01-17)
+--------------------
+Update on the build process, new maintainer, git tree
+to keep the changes. Fixes in this release include
+ * minor bug fixes
+ * build fixups and fixes for the build process
+ * a stub handler for SIGWINCH (still not fully supported)
+ * adding units to the levels (lin/log)
+ * tidied up code
+
+--------------------
+0.4.0b (2002-12-21)

+varying features) with all devices supported by the Linux wireless kernel
+extensions by Jean Tourrilhes.
+
+See the man page for an in-depth description of operation and configuration.
+
+
+2) Where to obtain
+------------------
+You can always find the latest version at:
+
+	http://eden-feed.erg.abdn.ac.uk/wavemon
+
+Please check this page for updates and for further information.
+wavemon is distributed under the GPLv3, refer to the file COPYING.
+
+
+3) How to build
+---------------
+wavemon uses autoconf, so that in most cases you can simply run
+
+	./configure
+	make
+	sudo make install
+
+to build and install the package. Type 'make uninstall' if not happy.
+Refer to the file INSTALL for generic installation instructions.
+
+If you have changed some of the autoconf files or use a git version, run
+	./config/bootstrap
+(requires a recent installation of 'autotools').
+

+Many people contribute to wavemon by reporting problems, suggesting various
+improvements, or submitting actual code. Here is a list of these people. Help
+me (gerrit@erg.abdn.ac.uk) keep it complete and exempt of errors.
+
+Christoph J. Thompson (cjsthompson@gmail.com) provided DESTDIR support for
+the installation process and contributed a Slackware build script, found in
+the contrib folder (2009-03-03).
+
+Tom Gordon to help fix a build error occurring under Puppy Linux, in wavemon
+version 0.5 (2009-02-06).
+
+Dave W. Capella (dave.capella@cornell.edu) provided modifications to build
+ipkg packages for mobile devices in 2002 (now in contrib/).
+
+Nelson A. de Oliveira provided helpful tips for choosing a sensible screen-size
+default, and helped much to reduce annoyances in keeping the configuration-file
+parser backward-compatible (0.6.7).
+
+Jonathan Lovelace  provided a patch to enable build on Gentoo (0.6.10).
+Hanno Boeck supplied a patch to improve the linking process (0.6.10).

+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+			  [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+			  [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+

+	    meantime, this test will reject xlc, which is OK, since
+	    our stdbool.h substitute should suffice.  We also test

+.TH WAVEMON 1 "JANUARY 2009" Linux "User Manuals"
+.SH NAME
+wavemon \- a wireless network monitor application
+.SH SYNOPSIS
+.B wavemon [-h] [-i
+.I ifname
+.B ] [-l] [-r] [-v]
+.SH DESCRIPTION
+.B wavemon
+is a ncurses-based monitoring application for wireless network devices. It displays continuously updated information about signal levels as well as wireless-specific and general network information. Currently, wavemon can be used for monitoring devices supported by the wireless extensions by Jean Tourrilhes <jt@hpl.hp.com>, included in kernels version 2.4 and higher.
+
+The wavemon interface is separated into several different sections, hereby referred to as "screens". Every screen displays information about distinct parameter types and/or in a special manner. For example, the "info" screen shows the current signal and noise levels as bargraphs, while the level histogram shows the exact same values as a level plot, so their development over time can be seen.
+On startup, you'll see one of the different monitor screens (which of the screens will actually be displayed depends on your configuration). On the bottom, you'll see a bar showing the available screens along with function key strokes.
+.LP
+These screens are currently implemented:
+.TP
+.B Info (F1)
+This is the most "conclusive" of the monitor screens. It displays a condensed overview of all available wireless-specific parameters and network statistics, as well as bar graphs of the current signal and noise levels. There are several sub-sections to further separate the information.
+
+At the
+.B Interface
+section, the name, ESSID and nickname of the current wireless interface are shown.
+
+Below, at the
+.B Levels
+section, you can see four bargraphs showing the quality of the link to the next station (if established), the level of the received signal, the current receiver's noise level and the signal-to-noise ration, which gives a good approximation of the overall signal quality. The colour of the signal level bargraph changes from red to yellow and green at fixed levels, while the colour of the noise level graph is adapted to the current signal level (it turns red when the signal-to-noise-ratio gets below 0dB). If the thresholds are associated with any actions, two arrows on the signal level graph will show the positions of the current thresholds. More on this topic later.
+
+The
+.B Statistics
+section displays packet and byte counters. The first four values, preceded RX and TX, show the current total number of packets received and transceived since the initialization of the interface. The following three values display the number of packets that were discarded from the interface because of invalid network ids, wrong encryption keys and other errors.
+
+Below, at the
+.B Info
+subsection, various wireless-specific parameters of the interface are displayed. What parameters are actually shown may vary and depends on the capabilities and the operation mode of your network device. The top line shows the current frequency the interface operates on, the sensitivity threshold of the receiver and the transmission power. Below, the operation mode of the interface (managed, ad-hoc...) and, if appropriate, the MAC address of the current access point are displayed. The third line shows the current data transfer speed in Mbit/s and the retransmission and fragmentation thresholds. Whether or not the details about encryption show up in the next line depends on the permissions of the user. Finally, the last line displays the power management parameters, if this feature is available and active.
+
+The last section, titled
+.B Network,
+shows - you guessed it - network parameters, such as the interface name and hardware address as well as the interface, netmask and broadcast IP addresses. These parameters are not wireless-related.
+
+Another keyboard shortcut for this screen is 'i'.
+.TP
+.B Level histogram (F2)
+This is a full-screen histogram plot of the signal/noise levels and the signal-to-noise levels. It shows the level changes with time. Below the plot, the key is shown. If available, the terminfo scanline chars are used in order to enhance the precision of the level plots, i.e. this screen will particularly look nifty in a xterm.
+.TP
+.B Access point list (F3)
+This screen provides a list of MAC addresses specifying the access points within range. This feature is currently _very_ rudimentary and may not even work for you. Stay tuned, as a more useable access point list is on its way.
+.TP
+.B Preferences (F7)
+This screen allows you to change all program options such as interface and level scale parameters, and to save the new settings to the configuration file. Select a parameter with <up> and <down>, then change the value with <left> and <right>. Please refer to the
+.B wavemonrc
+man page for an in-depth description of all available settings.
+.TP
+.B Help (F8)
+This page will show an online-help in the near future; it is currently not implemented.
+.TP
+.B About (F9)
+This screen contains information about the current
+.B wavemon
+release.
+.TP
+.B Quit (F10)
+The associated function key will immediately exit
+.B wavemon.
+An alternative keyboard shortcut for quitting is 'q'.
+.SH OPTIONS
+.IP -h
+print a short explanation of the command line arguments and exit.
+.IP "-i interface"
+override autodetection and use the specified interface.
+.IP -r
+generate random levels (for testing purposes).
+.IP -v
+dump the version number to stdout and exit.
+
+.SH ENVIRONMENT VARIABLES
+.IP "LC_NUMERIC"
+Influences the grouping of numbers if set. See also
+.BR locale (1).
+
+.SH FILES
+.I ~/.wavemonrc
+is the local configuration file for the user. Refer to the
+.B wavemonrc
+man page for an in-depth explanation of available settings.
+.SH BUGS
+While each release has been tested, bugs are sometimes inevitable.
+Please help to further improve the state of wavemon by sending all bug reports,
+and any suggestions or comments, to <gerrit@erg.abdn.ac.uk>. Thanks!

+.SH NAME
+wavemonrc \- wavemon configuration file
+.SH SYNOPSIS
+.B wavemon [-h] [-i
+.I ifname
+.B ] [-l] [-r] [-v]
+.SH DESCRIPTION
+.B wavemon
+stores its configuration parameters within the file ~/.wavemonrc in every user's home directory. This manpage provides an in-depth description of the available options. Every setting corresponds to a configuration item you'll find on the preferences screen within the program (F7 key).
+.P
+.B interface = <ifname>
+.RS
+.RE
+.B (Interface)
+.RS
+This parameter specifies, you guessed it, the name of the interface wavemon uses for operation. Only valid identifiers of existing wireless network devices are allowed, otherwise the program launch will fail.
+.P
+.RE
+.B stat_updates = <n>
+.RS
+.RE
+.B (Statistics updates)
+.RS
+This controls the intervals between updates of the statistics data. Range: 10..4000ms.
+.P
+.RE
+.B lhist_slot_size = <n>
+.RS
+.RE
+.B (Histogram update cycles)
+.RS
+This determines how many obtained statistics values are averaged into one level histogram slot. So, if your statistics update interval is 50ms and your histogram slot size is 4, the histogram is moved one slot further every 2 seconds. Range: 1..64.
+.P
+.RE
+.B meter_smoothness = <n>
+.RS
+.RE
+.B (Level meter smoothness)
+.RS
+Determines the responsiveness of level meters, tracking the moving average rather than following each new sample. The given value specifies the percentage of the history (the 'inertia') of preceding samples. A value of 0 disables this option. Range: 0..99%.
+.P
+.RE
+.B info_updates = <n>
+.RS
+.RE
+.B (Dynamic info updates)
+.RS
+With this setting, you can control the intervals between updates of the dynamic device parameters, i.e. those values that may change, but not frequently. Dynamic parameters are for example the current bitrate of your wireless link. Range: 1..60s.
+.P
+.RE
+.B override_auto_scale = (enabled|disabled)
+.RS
+.RE
+.B (Override scale autodetect)
+.RS
+Setting this parameter to "enabled" overrides the auto-detection of the bar graph and histogram scale boundaries, allowing you to specify your own scales.
+.P
+.RE
+.B min_signal_level, max_signal_level = <n>
+.RS
+.RE
+.B (Minimum signal level, Maximum signal level)
+.RS
+These parameters allow you to set the left and right boundaries of the signal level scales. Ranges: -128..-60dBm (minimum), -59..120dBm (maximum).
+.P
+.RE
+.B min_noise_level, max_noise_level = <n>
+.RS
+.RE
+.B (Minimum noise level, Maximum noise level)
+.RS
+These work similar to the signal boundary settings. Ranges: -128..-60dBm (minimum), -60..120dBm (maximum).
+.P
+.RE
+.B random = (enabled|disabled)
+.RS
+.RE
+.B (Random signals)
+.RS
+This switch controls a fancy random generator you can use for testing functions and scales.
+.P
+.RE
+.B lo_threshold_action = (disabled|beep|flash|beep+flash)
+.RS
+.RE
+.B (Low threshold action)
+.RS
+This function allows you to assign a warning facility to a defineable threshold at the lower end of the signal scale. It is meant for alarming you when a signal appears at the receiver.
+.P
+.RE
+.B lo_threshold = <n>
+.RS
+.RE
+.B (Low threshold)
+.RS
+This defines the low threshold. Makes only sense when the above setting is active. Range: -120..-60dBm.
+.P
+.RE
+.B hi_threshold_action = (disabled|beep|flash|beep+flash)
+.RS
+.RE
+.B (High threshold action)
+.RS
+This is similar to lo_threshold_action, only this time the threshold is at the upper end of the scale and the action is performed when the signal level drops below it. The acoustic signal is also different in order to be easily distinguishable from the lower one. Correctly adjusted, this little fellow will tell you when you should move closer to the base station.
+.P
+.RE
+.B hi_threshold = <n>
+.RS
+.RE
+.B (High threshold)
+.RS
+This defines the high threshold. Makes only sense when the above setting is active. Range: -59..120dBm.
+.P
+.RE
+.B startup_screen = (info|histogram|access points)
+.RS
+.RE
+.B (Startup screen)
+.RS
+This setting determines which of the screens will be shown at program startup.
