Q: understanding pcl-cvs code

Hi Stefan. I am currently digging in the pcl-cvs code to fix a flags problem. I suppose you can help me straighten things out for me regarding the code. The flags are stored in a structure with the following slots defaults persist desc qtypedesc hist-sym To me it looks like only `defaults' is being used. I would guess that hist-sym would contain a history list of arg-prefixed flags. That one contains a list of flags (which are list of strings), there are 4 such lists due to `cvs-shared-start' then followed by again 4 (shared?) flags which in case seem to nil Why are there more than one list of default flags? What is the intent of `cvs-shared-start' and `cvs-shared-flags'? Too me such shared flags should not be stored in the same list as default flags. Jarl
