 +====== CVS2RSS ======
  
 +Sometimes you want to monitor changes in a CVS server were you have access to install a script like [[http://rebma.cit.cornell.edu/~bs235/projects/cvs2rss/|this one]]. This is when the following script comes in handy. It fetches the needed data from the remote CVS server and converts it to RSS to read in your RSS reader.
 +
 +You need the [[http://www.bitfolge.de/rsscreator-en.html|feedcreator class]] and the cvs commandline utility.
