%text %{
This module provides support for building a new version of the
Perl executable.  This will be necessary on systems that do
not support shared libraries and may be necessary with C++
extensions.  

This module may only build a stripped down version of the
Perl executable.   Thus, it may be necessary (or desirable)
to hand-edit this file for your particular application.  To
do this, simply copy this file from swig_lib/perl5/perlmain.i
to your working directory and make the appropriate modifications.

This library file works with Perl 5.003.  It may work with earlier
versions, but it hasn't been tested.  As far as I know, this
library is C++ safe.
