Last change on this file since 1256 was 1256, checked in by bruno, 13 years ago

Begining of work on conf file introduction in mondo

  • create a new struct mr_ar_conf to store conf info
  • adds a static mr_ar_store_conf function to store conf file info in that struc
  • mondo.conf is now the .dist version
  • md5 not done yet

Not tested may not work at all nor compile

  • Property svn:keywords set to Id
