* src/* Everything but src/images/* and src/data/* add correct svn 
	properties with the commands:
	svn propset -R svn:mime-type text/plain src/
	svn propset -R svn:eol-style native src/
	svn propset -R svn:keywords Id src/
	See below why the Id keyword is enough. From svn help propset
	svn:keywords   - Keywords to be expanded.  Valid keywords are:
      URL, HeadURL             - The URL for the head version of the object.
      Author, LastChangedBy    - The last person to modify the file.
      Date, LastChangedDate    - The date/time the object was last modified.
      Rev, Revision,           - The last revision the object changed.
      LastChangedRevision
      Id                       - A compressed summary of the previous
                                   4 keywords.
