Hi Martin or Stacho I wanted to add a few sentences to the Wiki section: http://therion.speleo.sk/wiki/doku.php/contrib:versioncontrol It looks like the register command is disabled. http://therion.speleo.sk/wiki/doku.php?id=start&do=register I'm using Mercurial to maintain therion data under version control. For non-commmand line users that need a GUI we are using "EasyMercurial" (http://www.easyhg.org) Hg was chosen because this simple GUI was available and because Hg has a "large files extension" that handles binary image files really well. This was needed for the scanned images that underlie the map drawing.
