+/**
+ * This library allows SEC (Satellite Equipment Control) configurations
+ * to be retrieved. Each configuration is identified by a unique satellite_id.
+ *
+ * In order to make things as easy as possible for users, there are a set of
+ * defaults hardcoded into the library covering the majority of LNB types. When
+ * these are used, the standard back-compatable sequence defined in the DISEQC
+ * standard will be used - this will suffice for _most_ situations.
+ *
+ * UNIVERSAL - Europe, 10800 to 11800 MHz and 11600 to 12700 Mhz, Dual LO, loband 9750, hiband 10600 MHz.
+ * DBS - Expressvu, North America, 12200 to 12700 MHz, Single LO, 11250 MHz.
+ * STANDARD - 10945 to 11450 Mhz, Single LO, 10000Mhz.
+ * ENHANCED - Astra, 10700 to 11700 MHz, Single LO, 9750MHz.
+ * C-BAND - Big Dish, 3700 to 4200 MHz, Single LO, 5150Mhz.
+ * C-MULTI - Big Dish - Multipoint LNBf, 3700 to 4200 MHz, Dual LO, H:5150MHz, V:5750MHz.
+ *
+ * However, for the power user with a more complex setup, these simple defaults
+ * are not enough. Therefore, it is also possible to define additional SEC
+ * configurations in an external configuration file. This file consists of multiple
+ * entries in the following format:
+ *
+ * [sec]
+ * name=<sec_id>
+ * switch-frequency=<switching frequency (SLOF)>
+ * lof-lo-v=<low band + V + frequency>
+ * lof-lo-h=<low band + H + frequency>
+ * lof-lo-l=<low band + L + frequency>
+ * lof-lo-r=<low band + R + frequency>
+ * lof-hi-v=<high band + V + frequency>
+ * lof-hi-h=<high band + H + frequency>
+ * lof-hi-l=<high band + L + frequency>
+ * lof-hi-r=<high band + R + frequency>
+ * config-type=<none|power|standard|advanced>
+ * cmd-lo-v=<sec sequence>
+ * cmd-lo-h=<sec sequence>
+ * cmd-lo-r=<sec sequence>
+ * cmd-lo-l=<sec sequence>
+ * cmd-hi-v=<sec sequence>
+ * cmd-hi-h=<sec sequence>
+ * cmd-hi-r=<sec sequence>
+ * cmd-hi-l=<sec sequence>
+ *
+ * The sec_id is whatever unique value you wish. If it is the same as one of the hardcoded defaults, the configuration
+ * details from the file will be used instead of the hardcoded ones.
+ * The switch-frequency (or SLOF) indicates the point seperating low band frequencies from high band frequencies.
+ * Set this value to 0 if there is only one frequency band.
+ * The lof-lo-v is the frequency adjustment for V + low band (i.e. less than SLOF), or is used if switch-frequency==0.
+ * The lof-lo-h is the frequency adjustment for H + low band (i.e. less than SLOF), or is used if switch-frequency==0.
+ * The lof-lo-l is the frequency adjustment for L + low band (i.e. less than SLOF), or is used if switch-frequency==0.
+ * The lof-lo-r is the frequency adjustment for R + low band (i.e. less than SLOF), or is used if switch-frequency==0.
+ * The lof-hi-v is the frequency adjustment for V + high band (unused if switch-frequency==0).
+ * The lof-hi-h is the frequency adjustment for H + high band (unused if switch-frequency==0).
+ * The lof-hi-l is the frequency adjustment for L + high band (unused if switch-frequency==0).
+ * The lof-hi-r is the frequency adjustment for R + high band (unused if switch-frequency==0).
+ *
+ * config-type indicates the desired type of SEC command to use, it may be:
+ * none - No SEC commands will be issued (frequency adjustment will still be performed).
+ * power - Only the SEC power is turned on.
+ * standard - The standard DISEQC back compatable sequence will be issued.
+ * advanced - The DISEQC sequence described in the appropriate sec cmd string will be used.
+ *
+ * The cmd-<lo|hi>-<v|h|l|r> describes the SEC cmd string to use in advanced mode for each of the possible combinations of
+ * frequency band and polarisation. If a certain combination is not required, it may be omitted. It consists of a
+ * space seperated combination of commands - those available are as follows:
+ *
+ * tone(<0|1>) - control the 22kHz tone 0:off, 1:on
+ * voltage(<0|13|18>) - control the LNB voltage 0v, 13v, or 18v
+ * toneburst(<a|b>) - issue a toneburst (mini command) for position A or B.
+ * highvoltage(<0|1>) - control high lnb voltage for long cable runs 0: normal, 1:add 1v to LNB voltage.
+ * dishnetworks(<integer>) - issue a dishnetworks legacy command.
+ * wait(<integer>) - wait for the given number of milliseconds.
+ * Dreset(<address>, <0|1>) - control the reset state of a DISEC device, 0:disable reset, 1:enable reset.
+ * Dpower(<address>, <0|1>) - control the power of a DISEC device, 0:off, 1:on.
+ * Dcommitted(<address>, <h|l|x>, <v|h|l|r|x>, <a|b|x>, <a|b|x>) - Write to the committed switches of a DISEC device.
+ * The parameters are for band, polarisation, satelliteposition, switchoption:
+ * band - h:high band, l:low band
+ * polarisation - v: vertical, h:horizontal,r:right,l:left
+ * satelliteposition - a:position A, b: position B
+ * switchoption - a:position A, b: position B
+ * The special value 'x' means "no change to this switch".
+ *
+ * Duncommitted(<address>, <a|b|x>, <a|b|x>, <a|b|x>, <a|b|x>) - Write to the uncommitted switches of the a DISEC device.
+ * The parameters are for switch1, switch2, switch3, switch4, and may be set to position a or b.
+ * The special value 'x' means "no change to this switch".
+ *
+ * Dfrequency(<address>, <frequency in GHz>) - set the frequency of a DISEC device.
+ * Dchannel(<address>, <channel id>) - set the desired channel id of a DISEC device.
+ * Dgotopreset(<address>, <preset id>) - tell a DISEC satellite positioner to move to the given preset id.
+ * Dgotobearing(<address>, <bearing in degrees>) - tell a DISEQC terrestrial rotator to go to the
+ * given bearing (range -256.0 -> 512.0 degrees, fractions allowed).
+ *
+ * In the above DISEQC commands, <address> is the integer (normally in hex format) address of the
+ * diseqc device to communicate with. A list of possiblities is as follows:
+ *
+ * DISEQC_ADDRESS_ANY_DEVICE = 0x00
+ *
+ * DISEQC_ADDRESS_ANY_LNB_SWITCHER_SMATV = 0x10
