-# 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
