DDC::PP - pure-perl drop-in replacements for DDC::XS module
=head1 SYNOPSIS
 use DDC::PP;
 #... stuff happens ...
=cut
##======================================================================
## Description
=pod
=head1 DESCRIPTION
This package doesn't do anything but load the
pure-perl drop-in replacements for the L<DDC::XS|DDC::XS> modules.
See submodule documentation for details.
The code in this module is a pure-perl implementation of the original DDC C++ and XS code,
based on
L<DDC::XS|DDC::XS> v0.19 and L<DDC|http://sourceforge.net/projects/ddc-concordance/files/ddc-concordance/> v2.1.15.
Newer features of the C++ query parser and its XS interface may not be supported.
If you need to be 100% sure you're parsing queries exactly as the C++ DDC server does, use
the L<DDC::XS|DDC::XS> distribution linked to the appropriate version of the
underlying DDC C++ libraries.
If you would like to use the "real" C++ wrappers provided by L<DDC::XS|DDC::XS> when they are available
and use the pure-perl implementations as a fallback, see the L<DDC::Any|DDC::Any> module provided in
this distribution.
