dnl $Id$ dnl $URL$ dnl @synopsis AC_PYTHON_DEVEL([version]) dnl dnl Checks for Python and tries to get the include path to 'Python.h'. dnl It provides the $(PYTHON_CPPFLAGS) and $(PYTHON_LDFLAGS) output dnl variables. Also exports $(PYTHON_EXTRA_LIBS) and dnl $(PYTHON_EXTRA_LDFLAGS) for embedding Python in your code. dnl dnl You can search for some particular version of Python by passing a dnl parameter to this macro, for example ">= '2.3.1'", or "== '2.4'". dnl Please note that you *have* to pass also an operator along with the dnl version to match, and pay special attention to the single quotes dnl surrounding the version number. dnl dnl If the user wants to employ a particular version of Python, she can dnl now pass to configure the PYTHON_VERSION environment variable. This dnl is only limited by the macro parameter set by the packager. dnl dnl This macro should work for all versions of Python >= 2.1.0. You can dnl disable the check for the python version by setting the dnl PYTHON_NOVERSIONCHECK environment variable to something else than dnl the empty string. dnl dnl If you need to use this macro for an older Python version, please dnl contact the authors.

 * $Log: display.h,v $
 * Revision 1.23  2004/01/09 17:03:07  reinelt
 * initiated transfer to new driver architecture
 * new file 'drv.c' will someday replace 'display.c'
 * new file 'drv_MatrixOrbital.c' will replace 'MatrixOrbital.c'
 * due to this 'soft' transfer lcd4linux should stay usable during the switch
 * (at least I hope so)
