What does a source code control system do?
If you are creating or maintaining a text file---perhaps a document,
or a script, or a program---a source code control system can do
several things for you:
- It can keep track of the changes made to the file: what
was changed, when it was changed, and by whom.
- It provides a version numbering scheme so you can tell
which versions of a file are more recent.
- It can retrieve previous versions of your file, so that you
can retreat to an older version if you decide that the current
version is a bad idea, or if you want to see some text that
has since been changed or deleted.
- If you accidentally delete the current file, you can get
back the last version.
- If several people are working with the same file,
a source code control system can help you coordinate your work
and keep track of who did what, and when.
