"""Create a TAGS file for Python programs, usable with GNU Emacs.
usage: eptags pyfiles...
The output TAGS file is usable with Emacs version 18, 19, 20.
Tagged are:
- functions (even inside other defs or classes)
- classes
eptags warns about files it cannot open.
eptags will not give warnings about duplicate tags.
BUGS:
Because of tag duplication (methods with the same name in different
classes), TAGS files are not very useful for most object-oriented
python projects.
