Well,  following   this    discussion I   checked   the  regexps  more
exhaustively,  and modified  it  slightly (in  the previous version it
didn't treated well the case with several return values). Also I found
that the tags for global variables don't work. I mean that it works if
there is only one global variable in the line :-(. However I wonder if
this is important.

Regards,

Mario

================= otags script =================================
#!/bin/bash
#$Id: otags,v 1.6 1998/11/11 20:04:42 mstorti Exp mstorti $

# generates a TAGS file for a set of Octave .m files for use with
# Emacs.  Run from the command line as '$ otags' in the given octave
# directory and will generate a TAGS file.  If you want to include
# another directory add a line prior to the "*.m" line containing
# something like `--include=/path/to/other/directory/TAGS" \'.

# Tags are generated for functions and for global variables. For
# global variables it doesn't work for more than one global variable
# per line. :-(((

# Tags are also created for lines of the form '###key foobar' so that
# you can jump to this specific place just by typing
# `M-. foobar'. Note that tags are not generated for scripts so that
# you have to add a line by yourself of the form
# `###key <script-name>' if you want to be able to jump to it.
