Hi:

Thanks for replying. I have a couple of other questions.

This two step approach is a bit complicated for a common user (and the
aproach I want for the emacs package), so I will try to minimize the
number of steps to simplify things in the gtags-mode package.

I also try to avid using environment variables because in Emacs+Tramp
the remote environment variables are a bit tricky and may become
problematic to handle. SO let's make this the plan C.

1) Is possible to do everything in a single step with the command line?
I don't care if the command becomes long.

I tried the --gtagslabel=universal-ctags

But there is some problem with this option. Somehow it is not working
for me... when I use the --explain it still shows the built-in ones

3) Isn't gtags capable to find the ctags executable in my path? it is
not in /usr/local/bin/ctags, but it is in the PATH... so only ctags
works for me.

3.1) Is there something similar for ctagscom but from command line?


Best regards, and thanks again,
Ergus
