# ===========================================================================
# http://www.gnu.org/software/autoconf-archive/ax_pkg_swig.html
# ===========================================================================
#
# SYNOPSIS
#
# AX_PKG_SWIG([major.minor.micro], [action-if-found], [action-if-not-found])
#
# DESCRIPTION
#
# This macro searches for a SWIG installation on your system. If found,
# then SWIG is AC_SUBST'd; if not found, then $SWIG is empty. If SWIG is
# found, then SWIG_LIB is set to the SWIG library path, and AC_SUBST'd.
#
# You can use the optional first argument to check if the version of the
# available SWIG is greater than or equal to the value of the argument. It
# should have the format: N[.N[.N]] (N is a number between 0 and 999. Only
# the first N is mandatory.) If the version argument is given (e.g.
# 1.3.17), AX_PKG_SWIG checks that the swig package is this version number
# or higher.
#
# As usual, action-if-found is executed if SWIG is found, otherwise
# action-if-not-found is executed.
#
# In configure.in, use as:
#
# AX_PKG_SWIG(1.3.17, [], [ AC_MSG_ERROR([SWIG is required to build..]) ])
# AX_SWIG_ENABLE_CXX
# AX_SWIG_MULTI_MODULE_SUPPORT
# AX_SWIG_PYTHON
