+# 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
