# 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
