The Makefile hierarchy is currently set up to install everything under
/opt/themwi; however, if you are running 'make install' from the top, you can
change to any other install prefix (just like ./configure --prefix in the world
of Autotools) with INSTALL_PREFIX= variable.

Unlike /opt/freecalypso, /opt/themwi is much less rigid, i.e., you can change
this install location without breaking everything.  However, I have yet to work
out exactly how themwi-csw and themwi-smsc will locate the pieces they require
from themwi-nanp (libraries and header files), and there is a strong likelihood
that /opt/themwi/include and /opt/themwi/lib paths will be hard-coded in
themwi-csw and themwi-smsc component Makefiles.
