-- Program to create, set, or delete an alternate runtime library
-- Works by calling an appropriate target specific Makefile residing
-- in the default library object (e.g. adalib) directory from the context
-- of the new library objects directory.
-- Command line arguments are:
-- 1st: --[create | set | delete]=<directory_spec>
-- --create : Build a library
-- --set : Set environment variables to point to a library
-- --delete : Delete a library
-- 2nd: --config=<file_spec>
-- A -gnatg valid file containing desired configuration pragmas
-- This program is currently used only on Alpha/VMS
