Thanks David.  This gave me:
<----- cut here -----

Usage:
         preprocess.py <mode> <boost_root> [<source_file>]

Purpose:
         updates preprocessed version(s) of the header(s) in 
"boost\mpl\aux_\preprocessed" directory

Example:
         the following command will re-generate and update all 'apply.hpp' headers:

                 preprocess.py all f:\cvs\boost apply.cpp

 >----- cut here -----

However, despite what the subject line says, what I really need
is some way to do what's describe in the part of my post
quoted up above.  The code in preprocess.py doesn't help much.
It includes:

     os.system( "preprocess %s %s %s %s" % ( boost_root, mode, file,
       file_path ) )

which, I assume, invokes the:

   preprocess.cmd

in that directory.  I'm assuming the extension, 'cmd' is some windows
convention indicating an executable file since the above os.system call
above didn't include the extension.  Since I'm on linux, this wouldn't
work, AFAICT.  I did try:

<---- cut here ------

python preprocess.py msvc70 /home/evansl/prog_dev/boost-cvs/ro/boost 
apply.cpp
sh: line 1: preprocess: command not found
Traceback (most recent call last):
   File "preprocess.py", line 78, in ?
     , "boost\\mpl\\aux_\\preprocessed"
   File "preprocess.py", line 68, in main

 >---- cut here ------

I've also searched the pp.py file for clues by searching for 'template';
however, that wasn't much help either.

I'd appreciate any other suggestions for a linux user ;)

TIA.

-regards,
Larry
