Description of problem:

When I look for documentation about efax, I first open efax man page. In this man page I read: "Please read the fax man page first."
So, I open fax man page, and I fall on a page in french about mgetty+sendfax !
For french speaking beginners, this is very confusing. For several years I didn't understand I had to read the english man page because I didn't suspect it could gather informations on another software than french one...

I suggest to add somewhere in the header of french fax man page something like this:

"Attention, cette page documente la commande fax fournie par le paquet mgetty+sendfax. Celle fournie par le programme efax, qui n'a rien à voir avec mgetty+sendfax, peut être consultée en anglais via la commande : LANGUAGE=en man 1 fax"
