# 3 A useful python script: `cvsupchk`

Alternatively, in order to examine your sources for inconsistencies, you may wish to utilize the `cvsupchk` python script; which script is currently found in `/usr/ports/net/cvsup/work/cvsup-16.1/contrib/cvsupchk`, together with a nice `README`. Prerequisites:

1. `/usr/ports/net/cvsup` `#` `make extract`

2. python (also found in the ports collection :-))

3. a checkouts file for your collection of sources.

If you are updating your sources for the very first time, of course you do not have a checkouts file. After installing python and updating your sources (eg `/usr/ports`), you can check them thus:

    % /path/to/cvsupchk -d /usr -c /usr/sup/ports-all/checkouts.cvs:. | more

If you want to check your RELENG_4 sources:

    % /path/to/cvsupchk -d /usr -c /usr/sup/src-all/checkouts.cvs:RELENG_4 | more

In each case, `cvsupchk` will inspect your sources for inconsistencies by utilizing the information contained in the related checkouts file. Such anomalies as deleted files being present (aka stale files), missing checked-out files, extra RCS files, and dead directories will be printed to standard output.

In the next section, we will provide important, typical examples of source updating; which examples will show you the role of checkouts files and the dangers of negligent source management.
