[Ctags] Adding Prolog support using ptags

[<dja...@fr...>]

Hello,
I used for years a simple tags file producer for prolog files called ptag=
s (
http://www.cs.cmu.edu/afs/cs/project/ai-repository/ai/lang/prolog/util/pt=
ags/0.html)
it's compatible with ctags files so I was wondering how hard  would it=20
be to include this tool to exhuberant ctags ?

for now I'm doing this by hand (I'm working on  a logic program=20
compiler, runtime and bootstrap compiler in C, builtins in prolog like=20
language) :
ctags -R *
ptags *.pl -a tags   (it appends the result to the existing tags file)
but it doesn't have a recursive option so some time I'm doing something l=
ike
find ./  -iname "*.pl" -exec ptags {} -a tags ;
so I really don't know how the ctags's code base is structured and I'll=20
be glad to help someone who also would want to add prolog support to ctag=
s



Thanks for reading
