annotate Tools/scripts/parseentities.py @ 11239:577ea261bdf2 legacy-trunk

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Find the help.txt file relative to __file__ or ".", not in sys.path. (Suggested by Moshe Zadka, but implemented differently.) Add <<python-docs>> event which, on Unix, brings up Netscape pointing to http://www.python.doc/current/ (a local copy would be nice but its location can't be predicted). Windows solution TBD.
