Math-Random-Xorshift is a Perl module that contains a straightforward implementation of the Xorshift PRNG algorithm proposed by G. Marsaglia in 2003. The algorithm is extremely fast and passes the Diehard test, though it is not reliable enough statistically. This module is useful for games and similar applications.
PPM-Make is a Perl module that automates some of the steps needed to make a ppm (Perl Package Manager) package from a CPAN distribution. It attempts to fill in the ABSTRACT and AUTHOR attributes of Makefile.PL if these are not supplied, and also generates HTML documentation. ppm is used in the ActivePerl distribution. ActivePerl is primarily used on Windows and by corporations on other OSes.
The Tcl extension provides a small but complete interface into libtcl and any other Tcl-based library for Perl programmers. It lets you create Tcl interpreters (as Perl 5 objects), bind in commands to them (either Perl subroutines or C functions dynamically loaded with the DynaLoader extension), and execute Tcl code in those interpreters.
WWW-Analytics-MultiTouch is a tool and a Perl library for multi-touch Web analytics. Unlike typical last-session attribution Web analytics, multi-touch gives insight into all of the various marketing channels to which a visitor is exposed before finally making the decision to buy.
Fedora-Bugzilla is a Perl module that aims to expose a kinder, gentler interface to Fedora/RedHat's Bugzilla implementation, which has a large number of custom methods. In addition to the XML-RPC methods that Bugzilla makes available, there are also some things that can be accessed only via the Web/XML interfaces, such as the flags, attachments, and comments functionality. This package works to expose those as well.
The satpass script provides satellite visibility predictions, given the position of the observer and the NORAD element sets for the desired satellites. It can acquire the NORAD element sets directly from any site supported by Astro::SpaceTrack. It can acquire the observer's latitude and longitude from http://geocoder.us/, look up star positions in the SIMBAD catalog, and more.
Perl modules are notated in many different formats: "Foo/Bar/Baz.pm", "Foo::Bar", "Foo-Bar", etc. Module-Format allows one to take a list of modules in any format (including mixed ones) and output it in a consistent format that can be input to an installation program or an information querier.
