|

| 31 | .PP
|
|---|
| 32 | \fISvc\fR is the Shell Version Control system, patterned on RCS.
|
|---|
| 33 | It maintains a sequence of versions in archive files, so that new versions
|
|---|
| 34 | can be checked in (added to the archive), and old versions can be checked
|
|---|
| 35 | out (made available).
|
|---|
| 36 | To create an archive for \fIfile\fR, check it in with the \fB\-u\fR flag.
|
|---|
| 37 | This action will prompt for a log message and then create an archive called
|
|---|
| 38 | \fIfile,S\fR in the current directory, or in the subdirectory \fISVC\fR if
|
|---|
| 39 | it exists.
|
|---|
| 40 | The file will not be deleted, but will be made unwritable.
|
|---|
| 41 | .PP
|
|---|
| 42 | To update the file, check it out with the \fB\-l\fR flag.
|
|---|
| 43 | Then modify it, and check it back in, giving a new message when prompted.
|
|---|
| 44 | After this process has been repeated many times, the archive will contain
|
|---|
| 45 | the entire history.
|
|---|
| 46 | Any version can be checked out using the \fB\-r\fR flag.
|
|---|
| 47 | To get a printout of the history, use \fIsvclog\fR.
