how do I make ecb use the output of exuberant ctags ?

[humanitiesNerd]

From "Preferences -> supporting not-semantic sources" a customization buffer comes up

In it, the relevant variable seems to be

Ecb process non semantic files

But all there is to read is:

"See also 'ecb-non-semantic-parsing-function' "

And how do I find that paragraph ?

Thanks

I set (setq ecb-process-non-semantic-file 1) in my emacs init file but I can' t understamd if ecb is actually using the etags file
