NAME
    PAR::Packer - PAR Packager

DESCRIPTION
    This module implements the App::Packer::Backend interface, for
    generating stand-alone executables, perl scripts and PAR files.

    Currently, this module is used by the command line tool pp internally,
    as well as by the contributed contrib/gui_pp/gpp program.

    Since version 0.97 of PAR, this module and its related tools such as
    "pp" have been stripped from the PAR distribution and are now
    distributed as the "PAR-Packer" distribution so that PAR users need not
    necessarily have a C compiler.
