| * DESCRIPTION : Regression test for Linux filesystem permissions. |
| * AUTHOR : Jeff Martin (martinjn@us.ibm.com) |
| * HISTORY : |
| * (04/12/01)v.99 First attempt at using C for fs-regression test. Only tests read and write bits. |
| * (04/19/01)v1.0 Added test for execute bit. |
| * (05/23/01)v1.1 Added command line parameter to specify test file. |
| * (07/12/01)v1.2 Removed conf file and went to command line parameters. |
