Perl - System Dependencies

System Dependencies - Perl module P214

Perl code is remarkably portable, but even with the best will in the world, there are always one or two things to consider if you're writing code that's got to be equally at home on Windows XP, Linux and OS X. This module also covers the use of Perl to access Microsoft-specific DLLs, allowing you to write a program to handle your Word document or Excel spreadsheet directly.
