If found you 12# should call SWIG via $(SWIG). You can use the optional first argument to 13# check if the version of the available SWIG is greater than or equal to 14# the value of the argument. It should have the format: N[.N[.N]] (N is a 15# number between 0 and 999. Only the first N is mandatory.) 16# 17# If the version argument is given (e.g. 1.3.17), AC_PROG_SWIG checks that 18# the swig package is this version number or higher. 19# 20# In configure.in, use as: 21# 22# AC_PROG_SWIG(1.3.17) 23# SWIG_ENABLE_CXX 24# SWIG_MULTI_MODULE_SUPPORT 25# SWIG_PYTHON 26# 27# LAST MODIFICATION 28# 29# 2008-04-12 30# 31# COPYLEFT 32# 33# Copyright (c) 2008 Sebastian Huber <sebastian-huber@web.de> 34# Copyright (c) 2008 Alan W.
