| |
| -- 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 |
