27 -- Program to create, set, or delete an alternate runtime library.
29 -- Works by calling an appropriate target specific Makefile residing
30 -- in the default library object (e.g. adalib) directory from the context
31 -- of the new library objects directory.
33 -- Command line arguments are:
34 -- 1st: --[create | set | delete]=<directory_spec>
35 -- --create : Build a library
36 -- --set : Set environment variables to point to a library
37 -- --delete : Delete a library
39 -- 2nd: --config=<file_spec>
40 -- A -gnatg valid file containing desired configuration pragmas
42 -- This program is currently used only on Alpha/VMS
