Create a shar file

Hi,
 
I am using a module Mod2 containing one directory "foo_dir"
Mod2:
./foo_dir
This directory contains foo files
foo_dir:
./foo1
./foo2
./foo3
./foo4
...
I would like to shar the foo files during the compilation without having to
specify the name of the foo files (I have hundreds of them so I do not want
to maintain such a huge list of file names) .
I have tried to use "Command", but it needs files in parameter and not
directories....
 
Thanks for help,
 
Vincent
