+dnl @synopsis AC_PROG_SWIG([major.minor.micro])
+dnl
+dnl This macro searches for a SWIG installation on your system. If found you
+dnl should) SWIG via $(SWIG). You can use the optional first argument to check
+dnl if the version of the available SWIG is greater than or equal to the
+dnl value of the argument. It should have the format: N[.N[.N]] (N is a
+dnl number between 0 and 999. Only the first N is mandatory.)
+dnl
+dnl If the version argument is given (e.g. 1.3.17), AC_PROG_SWIG checks that the
+dnl swig package is this version number or higher.
+dnl
+dnl In configure.in, use as:
+dnl
+dnl AC_PROG_SWIG(1.3.17)
+dnl SWIG_ENABLE_CXX
+dnl SWIG_MULTI_MODULE_SUPPORT
+dnl SWIG_PYTHON
