My understanding is that the scholarly convention for describing clefs is the clef's note (g1, c1, f, G) followed by the line number, counted from the bottom. Thus on a five line staff, French violin clef is g1, treble clef is g2, soprano clef is c1, mezzo-soprano clef is c2, alto clef is c3, tenor clef is c4, baritone clef is c5 or f3, bass clef is f4, sub-bass clef is f5, gamma clef is G3 (where gamma in the bottom of the gamut [ gamma to ut ], a bass singer's low G ).
The merit of the scheme is that it specifies pitch unambiguously for the common five-line staff, chant four-line staff, which has a clef signature for c1 on any of the four lines, and Escorial, which has a six line staff, or for a staff with any other number of lines. It does, however, assume that the various specified notes fall on a line, which is not the case with a staff displaced by octaves, such as the common convention of notating a tenor line in tenor clef an octave down. Such cases, however, are normally notated as an octave (or more) up or down. LilyPond in my experience supports the cx (x=1,...) nicely for a five line staff. I haven't tried it out for other number of lines in the staff. I think also the fx (x=1,...).
