How to use CVS

CVS help:

man cvs
cvs -H < command name >

Finding code in the CVS database:

http://cmssw.cvs.cern.ch/cgi-bin/cmssw.cgi/

make a new CVS tag:

cvs import -m < message > < direction of the CVS tag > < name of the author > start
-m msg Log message.
e.g.:
cvs import -m "StopAnalysisHUN" UserCode /HUN-2_2_3/StopAnalysis/ akapusi start

checkout:

cvs co -r < version number > -d < destination directory name > < CVS tag name >
-r rev Check out revision or tag. (implies -P) (is sticky)
-d dir Check out into dir instead of module name.

e.g.(1):
cvs co -rV00-01-05 -d SusyAnalysis /PatCrossCleaner UserCode /SusyAnalysis/PatCrossCleaner
e.g.(2): checkout the HEAD
cd CMSSW_X_X_X/src/SusyAnalysis/
cvs co -d UserCode /< group name >/

add a new tag to a valid CVS tag:

cvs tag < CVS tag name >-< e.g. number >

e.g.:
cvs tag StopAnalysis -123456

checkout:

cvs co -r StopAnalysis -123456 -d SusyAnalysis UserCode /HUN-2_2_3/StopAnalysis

update:

cvs update

After this we have to check the code, because if another person modified it, it's possible that it doesn't run.

difference:

cvs diff

upload/commit:

cvs commit -m "I modified ..." < name of the modified file >
or
cvs tag < name of the code >< number of tag >
