configure.in:

  • Added examples/pxeconfigd.xinetd.in
  • Now we generate pxeconfigd.xinetd with the right prefix. So we can still use it for our debian package

21# AM_PATH_PYTHON([MINIMUM-VERSION], [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])
22# ---------------------------------------------------------------------------
23# Adds support for distributing Python modules and packages.  To
24# install modules, copy them to $(pythondir), using the python_PYTHON
25# automake variable.  To install a package with the same name as the
26# automake package, install to $(pkgpythondir), or use the
27# pkgpython_PYTHON automake variable.
28#
29# The variables $(pyexecdir) and $(pkgpyexecdir) are provided as
30# locations to install python extension modules (shared libraries).
31# Another macro is required to find the appropriate flags to compile
32# extension modules.
33#
34# If your package is configured with a different prefix to python,
35# users will have to add the install directory to the PYTHONPATH
36# environment variable, or create a .pth file (see the python
37# documentation for details).
38#
39# If the MINIMUM-VERSION argument is passed, AM_PATH_PYTHON will
40# cause an error if the version of python installed on the system
41# doesn't meet the requirement.  MINIMUM-VERSION should consist of
42# numbers and dots only.
