To make the LieTools package.

1. Decide on where you want things to go, and edit the beginning of
   LieTools/make/mkLieTools.mpl accordingly.  
     MapleDir := the top level directory where you keep your own Maple 
                 program files (I keep this separate from the directory
                 containing the Maple executables and libraries, which
                 are platform and version dependent).
      PLibDir := the name of the directory to hold your 'private library` files
                 (I suspect these files might be platform and version dependent, 
                 so I store them in a subdirectory of the directory where Maple
                 was installed.) If this doesn't already exist you'll have to 
                 create it by hand. You'll also have to uncomment the 
                     march('create',PLibDir,400);
                 in mkLieTools.mpl.
2. Start Maple and call 
       read(full_path_to_mkLieTools.mpl);
