Yes, m.proj2 was intended to replace m.proj. However, it does still need
lots of debugging and code cleaning. An inter version of it (seperate
directory) should not be necessary as the current version (m.proj2)
should work both ways. In other words with no options it will walk you
through the arguments. 

Also, I should mention that m.ll2db is another coordinate conversion
program I added. It is based on m.ll2u, but instead gets proj info from
the current GRASS projection. It can replace m.ll2u, m.u2ll, and
possibly others. Essentially it will convert GRASS database units to and
from Lat. Long.. The idea was that where m.ll2db could not work (eg. XY,
or Lat. Long. proj) the user could use m.proj2. The code for this
program should (hopefully) be alot cleaner than m.proj2.

Hope this helps.
