Thanks for these features.

But I would much prefer a way to set things on a per project (directory)
basis. Environment variables are global. If I setenv for perl projects,
they might interfere with my php projects.

I have made ggtags¹ automatically use .globalrc or gtags.conf at current
project root i.e. where GTAGS is so that I don't have to reset GTAGSCONF
for every project. It turns out I use this feature on almost every
project at least for ignoring certain subdirectories to cut down
uninteresting matches.
