#
# 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
