 From Snyder's descsription in "Flattening the Earth" of Rousilhe's 
the equations given on pages 19 to 20 of "Map Projecrtion 
Principles and Applications" (Yang, et al) appears to be the original 
It is unclear to me what the purpose of the tmerc<-->Semi-Stereo 
later in the same book and others.

Upon closer reading, I'll correct my earlier statement to: full forward 
inverse material is included.  The only problem at the moment is that
some symbols are not defined and guesses need to fill in the blanks.
And, of course, the nasty habit of using the lower-case L as a symbol.
Currently working on retypesetting to American nomenclature/symbols.
(\phi, \lambda) not (B,l).

Hopefully, bench mark conversions can be located later.
