-
--- 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
