What do you call the tags in Subversion and CVS that add automatic content?

Things like $log$ and $version$ which add data upon check-in to the file. I'm interested in seeing the other ones and what information they can provide, but I can't get much info unless I know what they are called. Thanks.

• Both Subversion and CVS call them Keywords.

  Have a look in the SVN manual here (scroll down to svn:keywords) or here for CVS.

  From Dave Webb

• In SVN these are simply called "properties". You can read about them in the SVN book:

  Err, so, are they called properties or keywords? Oh, I see. In SVN you can associate arbitrary metadata, called "properties", with versioned files; some of the properties you can set are to set up keyword substitution in the files themselves.

• These are Keyword substitutions. The link to Red-Bean's book version 1.4 is here: http://svnbook.red-bean.com/en/1.4/svn.advanced.props.special.keywords.html.

  Subversion's built-in keywords are:

  • Date / LastChangedDate
  • Revision / Rev / LastChangedRevision
  • Author / LastChangedBy
  • HeadURL / URL
  • Id

  The keywords are case sensitive, and remember to surround them with $.
