I was engaged in the development of FORTRAN programs that were both
user-extendable and had one and the same source code for a variety of
platforms. The trick we played was that we included a number of 'slots' in
the code, where we called dummy subroutines. The user could include his own
features by replacing one of those dummies and then re-linking the program
from the .lib files we supplied along with the .exes. The re-linking was not
considered a problem since the user needed to have a compiler and a linker
for his platform anyway.

This technique may provide a way to allow users to extend POV without
compromising on platform independence.

Happy new year to all of you.
