==Setting up CVS access from Linux/Unix==
*To understand the codes for a CVS update, see page 121 of CVS users guide, section A.16.2.
#	Valuable resource for understanding ssh:

#	Setting up SSH access from "localbox" to "remotebox": <BR> <U>Localbox:</U>
#*	ssh-keygen -t rsa [use a passphrase]
#:	NOTE: Put the "id_rsa" (private file) in ~/.ssh.  There should only be one of these on a 	machine account.
#:	NOTE: Put the “id_rsa.pub�? (public file) in ~/.ssh as “authorized_keys�? on remote machines; see “Remotebox�? below.
#*	scp identity.pub skboyd@remotebox: [don't forget the last colon]
#*	in ~/.bashrc:
#*	export CVS_RSH=ssh
#*	export CVSROOT=:ext:skboyd@m177.enme.ucalgary.ca:/localhost/cvsroot
#*	eval `ssh-agent` {use the funny back single quotes} 
:<BR><U>Remotebox:</U>
#*	cat identity.pub >> ~/.ssh/authorized_keys
#	To avoid writing your passphrase every time you log on, run: 
#*	ssh-add
#:	Should work if ssh-agent is already running (eval `ssh-agent`  in the .bashrc file).
#	Do the following to limit access to cvs for the users:
#*	edit the public key installed in the .ssh/authorized_keys file with the following at the beginning of the public key line:
#:		command="/usr/bin/ssh server"

 <U>NOTES ABOUT KEYS</U>
 Remember, the "authorized_keys" file is a concatenation of public (id_rsa.pub) keys, 
 and the "id_rsa" is the private key.  
 Every user on every computer should only have ONE "id_rsa" file, 
 but can have multiple "id_rsa.pub" files concatenated into
 their "authorized_keys" file.

===Using CVS from a command line===
# To find a difference:
#* <code> $ cvs diff mylocalfile.cxx </code>
# To add a new file:
#* <code> $ cvs add mynewfile.cxx </code>
#* <code> $ cvs commit mynewfile.cxx </code>
# To update local file:
#* <code> $ cvs update -dCP </code>
#: or
#* <code> $ cvs update -dCP myfile.cxx </code>
# To check if a more recent version is available:
#* <code> $ cvs diff myfile.cxx </code>
#:  or
#* <code> $ cvs update </code> 
# To update CVS repository:
#* <code> $ cvs commit mylocalfile.cxx </code>
