gedit .cshrc.local
Add these lines to the bottom of it:
setenv CVSROOT /u/s/i/sinclair/CVS
setenv CVSEDITOR gedit

cvs update
	-> updates all files in project folder; shows which files have been changed / not added since last time

cvs commit -m "message"
	-> saves the changes you've made.  Message can be anything you want it to be - no one will see what you write there.

cvs add file.ext
	-> add the file to the server.  You need to do this in order to actually put on the server.  Do this, then cvs commit 		to store.
