1.1 What is CVS?
CVS is a version control system. Using it, you can record the history
of your source files.
For example, bugs sometimes creep in when software is modified, and
you might not detect the bug until a long time after you make the
modification. With CVS, you can easily retrieve old versions to see
exactly which change caused the bug. This can sometimes be a big help.
You could of course save every version of every file you have ever
created. This would however waste an enormous amount of disk space.
CVS stores all the versions of a file in a single file in a clever way
that only stores the differences between versions.
CVS also helps you if you are part of a group of people working on the
same project. It is all too easy to overwrite each others' changes
unless you are extremely careful. Some editors, like GNU Emacs, try to
make sure that the same file is never modified by two people at the
same time. Unfortunately, if someone is using another editor, that
safeguard will not work. CVS solves this problem by insulating the
different developers from each other. Every developer works in his own
directory, and CVS merges the work when each developer is done.
Essentially CVS is the tits for projects once you understand how to use
it, it has Windows, Mac and Unix frontends. CVS allows you to rollback
changes to your project, track changes and essentially if you fuck up,
CVS will help you return to sanity.
