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