5# SYNOPSIS
6#
7# AC_PROG_SWIG([major.minor.micro])
8#
9# DESCRIPTION
10#
11# This macro searches for a SWIG installation on your system. If found you
12# should call SWIG via $(SWIG). You can use the optional first argument to
13# check if the version of the available SWIG is greater than or equal to
14# the value of the argument. It should have the format: N[.N[.N]] (N is a
15# number between 0 and 999. Only the first N is mandatory.)
16#
17# If the version argument is given (e.g. 1.3.17), AC_PROG_SWIG checks that
18# the swig package is this version number or higher.
19#
20# In configure.in, use as:
21#
22# AC_PROG_SWIG(1.3.17)
23# SWIG_ENABLE_CXX
24# SWIG_MULTI_MODULE_SUPPORT
25# SWIG_PYTHON

5# SYNOPSIS
6#
7# AC_PYTHON_DEVEL([version])
8#
9# DESCRIPTION
10#
11# Note: Defines as a precious variable "PYTHON_VERSION". Don't override it
12# in your configure.ac.
13#
14# This macro checks for Python and tries to get the include path to
15# 'Python.h'. It provides the $(PYTHON_CPPFLAGS) and $(PYTHON_LDFLAGS)
16# output variables. It also exports $(PYTHON_EXTRA_LIBS) and
17# $(PYTHON_EXTRA_LDFLAGS) for embedding Python in your code.
18#
19# You can search for some particular version of Python by passing a
20# parameter to this macro, for example ">= '2.3.1'", or "== '2.4'". Please
21# note that you *have* to pass also an operator along with the version to
22# match, and pay special attention to the single quotes surrounding the
23# version number. Don't use "PYTHON_VERSION" for this: that environment
24# variable is declared as precious and thus reserved for the end-user.
25#
26# This macro should work for all versions of Python >= 2.1.0. As an end
27# user, you can disable the check for the python version by setting the
28# PYTHON_NOVERSIONCHECK environment variable to something else than the
29# empty string.
30#
31# If you need to use this macro for an older Python version, please
32# contact the authors. We're always open for feedback.

7# SWIG_PYTHON([use-shadow-classes = {no, yes}])
8#
9# DESCRIPTION
10#
11# Checks for Python and provides the $(SWIG_PYTHON_CPPFLAGS), and
12# $(SWIG_PYTHON_OPT) output variables.
13#
14# $(SWIG_PYTHON_OPT) contains all necessary SWIG options to generate code
15# for Python. Shadow classes are enabled unless the value of the optional
16# first argument is exactly 'no'. If you need multi module support
17# (provided by the SWIG_MULTI_MODULE_SUPPORT macro) use
18# $(SWIG_PYTHON_LIBS) to link against the appropriate library. It contains
19# the SWIG Python runtime library that is needed by the type check system
20# for example.
