+# 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
