+#
+# SYNOPSIS
+#
+#   AC_PROG_SWIG([major.minor.micro])
+#
+# DESCRIPTION
+#
+#   This macro searches for a SWIG installation on your system. If
+#   found you should call SWIG via $(SWIG). 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), AC_PROG_SWIG checks
+#   that the swig package is this version number or higher.
+#
+#   In configure.in, use as:
+#
+#     AC_PROG_SWIG(1.3.17)
+#     SWIG_ENABLE_CXX
+#     SWIG_MULTI_MODULE_SUPPORT
+#     SWIG_PYTHON

+# DESCRIPTION
+#
+#   Locates an installed Perl binary, placing the result in the

+#   and failing that searches for perl in the given path (which

+#   VALUE-IF-NOT-FOUND, which defaults to 'perl'.
