A reminder here: I only speak for libproj4.  Proj[4] was originally my name 
for the projection system prior to its adoption into software like cs2cs and 
other material associated with maptools.

The libproj4 distribution from my site contains an application program called 
lproj ("l" for limited because the Tchebychev approximation code had been 
removed from proj).  lproj runs almost identically with my older proj[4] and 
neither product had/have anything related to datum control/conversions and 
some other manipulations unrelated to projections.

The whole religious complexion of the modern world is due
to the absence from Jerusalem of a lunatic asylum.
