You can put regular expressions for etags in a file.  Have a look at the
info file of Emacs (node Etags Regexps) or the output of `etags --help'
(look for REGEXFILE).

Note that if you call etags from a Makefile it is probably more clear
and less prone to error to just put the --regex arguments on the
command line in makefile itself.
