ActivePerl is a language interpreter for Perl for Windows. Once installed, scripts developed under this language will allow you to execute such scripts as CGI's in Windows. The program is based on the multi-platform, multi-language IDE for what the developers call "end-to-end dynamic web application development."
If you are a Perl programmer, you'll find it easy to create, test and debug all of your code in ActivePerl. The Komodo IDE offers several advanced editing and debugging tools for dynamic languages and client-side Ajax technologies. It also includes some intuitive tools for team development and customization.
ActivePerl also includes The TDK Pro Pack which features application builders for Windows, Mac OS X, Linux, Solaris, AIX and HP-UX. It also features a suite of tools to speed-up development time and improve code quality.
If Perl is your speciality, you'll be spoilt for choice amongst the features that ActivePerl offers you.
