I like the idea, but I have long found the idea of putting this type of logic (including VCS-awareness) in newvers.sh itself something that is prone to turn what should be a rather simple script into a ... mess. What I have been using for several months has been a modified newvers.sh that uses an externally-defined function (from a file that is sourced) to handle whatever VCS-specific things I think are appropriate. (Thus, folks who want to use one VCS don't need to have newvers.sh test for VCSen they don't use; they could also provide a sample file that provides the function. An installation could use a symlink to point to the function definition of choice.... We could even have a "kitchen sink" default, that goes through all the hoops & gyrations the current code does, if folks want that.) Extending that to define a function for compiler-awareness should be straightforward -- and (IMO) avoid cluttering newvers.sh even more. Caveat: I'm not a committer. I do exercise newvers.sh a bit more than many folks, though. :-} Peace, david -- David H. Wolfskill david@catwhisker.org Taliban: Evil men with guns afraid of truth from a 14-year old girl.
