=head1 NAME

Math::Symbolic::Parser::Precompiled - Precompiled Math::Symbolic Parser

=head1 DESCRIPTION

This module is a precompiled version of the Parse::RecDescent grammar
that can be found in $Math::Symbolic::Parser::Grammar. It is used internally
to improve startup performance. Please use the new() method in the
Math::Symbolic::Parser namespace to generate new parsers.

Also note that some modules on CPAN (like Math::SymbolicX::Complex, etc.) modify
the parser which is stored in $Math::Symbolic::Parser at the time of loading
the module.

=head1 AUTHOR

Please send feedback, bug reports, and support requests to the Math::Symbolic
support mailing list:
math-symbolic-support at lists dot sourceforge dot net. Please
consider letting us know how you use Math::Symbolic. Thank you.

If you're interested in helping with the development or extending the
module's functionality, please contact the developers' mailing list:
math-symbolic-develop at lists dot sourceforge dot net.

=head1 SEE ALSO

New versions of this module can be found on
http://steffen-mueller.net or CPAN. The module development takes place on
Sourceforge at http://sourceforge.net/projects/math-symbolic/
