A while ago I wrote to this list about some work I'd done in etags. This was one of the features -- that is, I made "etags -u" work in etags mode, not just ctags mode. The overall thrust of the project was to combine the use of a config file in the source tree with auto-updating. The former I considered necessary to (1) avoid dealing with Makefiles and whatnot (and, building tags in the source tree is much nicer when doing out-of-tree builds...), and (2) make it so that Emacs could run "etags -u" on save without needing to teach it about the correct command line arguments -- they are in the config file (ages ago I did this same project but stored the command line arguments in the TAGS file; but this patch was never accepted). Anyway, this all works and I am happy to send the patches if you want them. I personally switched to GNU Global in the meantime; it has these features and a few more, though it too is not without its warts. I suppose I could push my branch to git if that would be convenient. Just let me know. Tom
