|
| 7 |
also search.
|
| 8 |
* If SCRAM_ARCH is forced via command-line e.g. "scram -a <arch> list <ver>"

|
| 49 |
|
| 50 |

* No more project.lookup file to keep track of install projects.
|
| 83 |
SCRAM now can look under <cmspath>/<arch> to find out the
|
| 84 |
installed projects. Extra SCRAM configuration for keeping tracks
|
| 85 |

etc.
