-(* This is a simple gtk interface to the Coq-like pretty printer cicPp for *)
-(* cic terms exported in xml. It uses directly the modules cicPp and *)
-(* cicCcache and indirectly all the other modules (cicParser, cicParser2, *)
-(* cicParser3, getter). *)
-(* The syntax is "gtkInterface[.opt] filename1 ... filenamen" where *)
-(* filenamei is the path-name of an xml file describing a cic term. *)
-(* The terms are loaded in cache and then pretty-printed one at a time and *)
-(* only once, when the user wants to look at it: if the user wants to look at *)
-(* a term again, then the pretty-printed term is showed again, but not *)
-(* recomputed *)
