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 +# +# LICENSE +# +# Copyright (c) 2008 Sebastian Huber <sebastian-huber@web.de> +# Copyright (c) 2008 Alan W.
