CMS is a Web-based Content Managment System written in Perl. This system allows a group of people to share files and work on them without interfering with the work of others. This is done by checking-out, checking-in and reserving files. By checking-out a file reserved, you make sure everyone else knows you are working on the file. This ensures that no one takes the file with the intention on making changes to it. Once you are done making changes, you check-in the file hence making it available to the others. The system is very easy to use and install. Almost no instructions are necessary. It is heavily based on JavaScript and cookies, so make sure you are using a recent browser.
