A package manager is also supplied with ActiveState's Win32 port of Perl. The executable, "ppm" can interactively pull down precompiled Perl modules from ActiveState's FTP server and install them for you. It comes with support for querying for a list of installed packages and updating them dynamically. It's a replacement for the CPAN module (implementing functionality roughly similar to "perl -MCPAN -e shell"), which is basically a Unix critter, and doesn't work so good under Windows.
