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. Popular ActiveState's ActivePerl distribution comes with PPM included, other distributions can use PPM after acquiring and building PPM module from CPAN.[3]
PPM uses so called “PPM Repositories”, collections of pre-compiled modules. These repositories contain a large variety of modules, published on CPAN.[4]
As of ActivePerl 5.28, PPM is no longer supported.[5]
