Computer System FAQ

 

When several persons are working on the same computer files, it is a good idea to use a revision control system (RCS) to make sure they are not overwriting each others changes. Also, RCS is a good idea since it allows to backtrack which changes have been made when and by whom, and to restore older versions of a file.

The directories under /data/common/matlab contain such files which are edited by several persons.

Therefore, these directories should only be accessed using our revision control system.

You can use the two programs "checkin" and "checkout" to access these archive-directories.

If you want to modify a program, use the checkout program to copy (ie, checkout) the program from the archive to your working directory. This also locks the file in the archive, i.e., nobody else may checkout the same program unless you have "checked in" your copy.

Then, you can edit the copy in your working directory as you like.

When you are done, use "checkin" to check your modified version back into the archive. During the checkin operation, you will also be prompted for a short comment (about one line), summarizing your changes to the program. Your comment will be stored together with the program.

For further details, please type "checkin" (or "checkout") on the command line to get an info-message.
