OK. STEPS 1 and 2 are for Kyuchul only, STEPS 3 and 4 for all of us.

STEP1 -- Initial setup

Firstly, youare going to create /home/projects/ameritech/korean/.CVS as the
repository. This is the place where the backups kept by CVS live.
Ordinarily, the only program that touches this is cvs. To create
the repository you say

cvs -d /home/projects/ameritech/korean/.CVS init

Now, you need to make sure that the repository is readable and
writeable by the right people. In our case, you me and Mary
are members of the group compling, and we want everything
to be group writeable, and we want things to be set
up so that subdirectories get their group ownership from
the enclosing directory. Thus

cd .CVS
chgrp -R compling .
chmod ug+rwsx CVSROOT
chmod ug+rwsx .

At this point (I think) permissions are correctly set, (NB. This part is
a one time only setup of .CVS, and violates the 'ordinarily' condition
stated above). If /home/projects/ameritech/.CVS exists already and has
the right permissions, you should instead start with STEP2

STEP2  -- Import some files

Suppose you have a directory called

/home/kyoon/database_paper

that contains a draft of the paper.

You can import it with

cd /home/kyoon/database_paper

cvs -d /home/projects/ameritech/korean/.CVS import -m "Initial checkin" dbpaper HW
HW_0

The last two arguments are required, but can for all practical purposes be
ignored. they can be anything you like: but there has to be something. The
message "Initial checkin" can again be any double quoted string. It is
recorded in the log file.

At this point you have a version of the database paper stored in the
repository under the name dbpaper. You can now delete (or if you are
more cautious, put on one side) the original in /home/kyoon/database_paper

STEP 3 -- checking out a copy

If you are Kyuchul
Check out a copy of the paper with

cd /home/kyoon/papers (or somewhere else of your choice)

cvs -d /home/projects/ameritech/korean/.CVS checkout dbpaper

If you are Mary, you might do the same thing but
in  /home/mbeckman/journals


cd /home/mbeckman/journals

cvs -d /home/projects/ameritech/korean/.CVS checkout dbpaper

The two copies exist separately, but refer to the same
shared repository, which will help keep them consistent,
so long as we remember to use CVS correctly.


STEP 4 -- working with CVS

You can get here two ways, either by doing steps 1-3 or by jumping in to
a pre-existing directory managed by CVS

cd dbpaper

cvs update

-- this ensures that your directory is current. It may find changes
made by others which it will try to incorporate for you. This is
only going to happen if other people have had the chance to work
on the files, so cvs update isn't really needed if you have just
gone through steps 1-3 and the directory is completely new. However,
it is good to get in the habit of doing cvs update frequently.

... make changes to the files using whatever editor etc you
like...



if you create a new file called foo that should be in the
repository, remember to say

cvs add foo

to tell CVS that you care about this.

if you just edit existing files, no need to do anything special,
CVS already has knowledge of these and will track them for you.

Finally, at the end of your editing session, you will have a
beautiful version of the paper that you now want to add back into
the repository.

First, make sure that your version is current. It could be that
someone else has made changes since you started working with the
files, so you have to do.

cvs update

Next, send the changes back to the repository with

cvs commit

Congratulations, you have now improved the paper. That's everything.

Best
