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