To compile and install xd3d and its related programs, you must have a
Fortran 77 and a C compiler. The X11 library libX11.a and the X.h
include file must be present on your computer.

The installation steps are the following:

1. Go to the root directory of xd3d (where you found this file)
2. type
  ./configure
and answer a few questions.
3. type
  make clean
4. type
  make
5. type (eventually)
  make install

You may have to be root to perform this last step and be allowed to
write in some system directories like /usr/local

Instead of step 2, you can build your own RULES file manually:

2.1 choose one of the RULES.xxx (corresponding to your OS or a "close" one)
and type
  cp RULES.xxx RULES
2.2 edit the RULES file and configure what is missing
(i.e. replace every "Please_Configure" by the good answer)
2.3 type
  ./makedeps

You may have to do it this way if /bin/csh is not present on your
computer since "configure" and "makedeps" are written in csh (in this
case you'll have to skip step 2.3, and the only side effect will be
that you will not be able to change automatically the memory allowed
to xd3d).

If you have troubles with the "normal" procedure, try the "manual" one.
