If found you 12238106Sdes# should call SWIG via $(SWIG). You can use the optional first argument to 13238106Sdes# check if the version of the available SWIG is greater than or equal to 14238106Sdes# the value of the argument. It should have the format: N[.N[.N]] (N is a 15238106Sdes# number between 0 and 999. Only the first N is mandatory.) 16238106Sdes# 17238106Sdes# If the version argument is given (e.g. 1.3.17), AC_PROG_SWIG checks that 18238106Sdes# the swig package is this version number or higher. 19238106Sdes# 20238106Sdes# In configure.in, use as: 21238106Sdes# 22238106Sdes# AC_PROG_SWIG(1.3.17) 23238106Sdes# SWIG_ENABLE_CXX 24238106Sdes# SWIG_MULTI_MODULE_SUPPORT 25238106Sdes# SWIG_PYTHON 26238106Sdes# 27238106Sdes# LAST MODIFICATION 28238106Sdes# 29238106Sdes# 2008-04-12 30238106Sdes# 31238106Sdes# COPYLEFT 32238106Sdes# 33238106Sdes# Copyright (c) 2008 Sebastian Huber <sebastian-huber@web.de> 34238106Sdes# Copyright (c) 2008 Alan W.
