Perl Package Manager (PPM) is a Perl utility intended to simplify the tasks of locating, installing, upgrading and removing software packages.
It can determine if the most recent version of a software package is installed on a system, and can install or upgrade that package from a local or remote host.
[1][2] PPM is widespread on Microsoft Windows systems, which often lack the C and C++ compilers necessary to build some Perl modules.
These repositories contain a large variety of modules, published on CPAN.
[4] As of ActivePerl 5.28, PPM is no longer supported.
