+Low requirements on client-side and server-side environment, to keep TWiki deployment as broad as possible is a key element of the [[TWikiMission]]. Strict W3C and ECMA standards compliance is also a mandate. These requirements are amended from time to time as technology progresses.
 
-TWiki is written in **Perl 5** and also uses some **shell commands**. It also requires that **GNU RCS** (Revision Control System) is installed on the same system. The current implementation runs best on a Linux machine, but it can also run with Microsoft Windows.
