Usage: $program [-c <commonpathes>] [-h] [-s <timestamp>] path1[=path1] ... pathN[=pathN] |
| 48 |
|
| 49 |
-c Filename containing common pathes not to include in the package |
| 50 |
|
| 51 |
-s Timestamp source. |
| 52 |
The path to a file to be used as the base timestamp for prototype |
| 53 |
operations. If this is specified, all source file creation times |
| 54 |
are compared to the creation time of this file. Files created |
| 55 |
*before* this time will be excluded from the prototype. |
| 56 |
|
| 57 |
-h Display brief usage. |
| 58 |
|
| 59 |
pathN The remainder of arguments to this command will be specified |
| 60 |
directly to pkgproto. These arguments specify which paths are to |
| 61 |
be included in the prototype. This can be specified as |
| 62 |
pathX=pathY to use a different prefix for files in the prototype |
| 63 |
than were present on the build system. |
