Hehe, yes :-)

Background: when creating tools/perf/ i cherry-picked all the nice 
Git libraries into tools/perf/util/, to give a standard environment 
for all tooling things that might come up in the future.

Some of those are not used yet but it looked more logical to pick up 
whole pieces - some already gained uses. For example config.c is not 
truly used yet, but very much expected to have a role in the future.

( The only invasive thing i had to do was the s/git_/perf_/ mass 
  rename across all the files - having 'git_' in perf looked
  quite confusing. )

And our general experience with the Git libraries in 
tools/perf/util/* is: we love them!

For example parse-options.c is a striking improvement compared to 
getopt.h we used before, and all the other facilities are sane and 
straight to the point as well. So in this sense 'perf' is an ... 
interesting cross-discipline 'fork' of Git's generic libraries.

The auto-generation of everything out of Documentation/*.txt is 
another thing we picked up, and that's very nice too.

One bookeeping issue: i found few explicit credits in those files - 
so i noted in the changelog that i took them from Git and i noted 
the specific upstream Git sha1 when i copied them. Would be nice to 
update each file with names to make credit more explicit:
