This is the FAQ for usage of CVS-BF:

-> Error Message (key: admin)
	> *PANIC* administration files missing	
   Diagnosis:
	bad folder, remove folder and checkout from scratch. 

-> Error Message (key: co):
	cvs checkout: cannot exec co: No such file or directory
   Diagnosis: you need RCS package, it contains 'co' program to check out
	files from CVS repository. See http://www.slac.stanford.edu/BFROOT/doc/Computing/www/Tools/RequiredSoft/#rcs

-> Error Message: (key: permission)
	> Sorry, you don't have read/write access to the history file 
	> <history> Permission denied
   Diagnosis: There might be two reasons: A. You're not in 
	g-babar:community group, type 'pts mem g-babar:community | grep 
	<your-uid>' to verify this. If so, write to chee@slac.stanford.edu.
	B. You have not convert your CVSROOT to AFS format. Old format: 
	uid@host:/path should be converted to 
	/afs/slac.stanford.edu/g/babar/repo.

-> Error Message: (key: HP)
	> cvs co bbsim
	> "morgan.slac.stanford.edu: morgan.slac.stanford.edu: cannot open"
	> (or "morgan.slac.stanford.edu: morgan.slac.stanford.edu: not 
	> found") cvs [checkout aborted]: premature end of file from server
   Diagnosis: 
	For HP machines (it uses 'mersh' instead of 'rsh'), do the 
	following:  setenv CVS_RSH remsh

-> Error Message: (key: patch, HP)
	> patch is not yet a supported command
   Diagnosis: 
	The patch program on HP does not work with CVS. Please see 
	"Required Software" page for how to port GNU patch. Make sure patch 
	is in PATH and ahead of HP's patch.

-> Error Message: (key: patch, HP) 
	"segmentation fault" (during 'cvs update' on HP)?
   Diagnosis: 
	The patch program on HP does not work with CVS. Please see 
	"Required Software" page for how to port GNU patch. Make sure patch 
	is in PATH and ahead of HP's patch.

-> Error Message: (key: patch)
	> cvs update
	> P FOO/foo
	> Too many file arguments.
	> cvs update: could not patch foo; will refetch 
   Diagnosis: The patch program on your machine does not work with CVS.
	Please see "Required Software" page for how to port GNU patch. Make
	sure patch is in PATH.

-> Error Message: (key: HP)
	> rcmd: socket: Permission denied
   Diagnosis: the rsh (or remsh on HP) must have uid-s bit set to call rcmd
	with root privilege. Do 'chmod u+s rsh' (or chmod u+s remsh on HP)
	to fix this problem. The result should be "-rwsr-xr-x".

-> Question: Do I need to put "morgan.slac.stanford.edu " into my .rhosts?
   Answer: 
	Not anymore, the new CVS establishs two way connection with just
	one 'RSH', user needs to put "client-machine user-name" into 
	.rhosts on server only, it is no longer needed to put 
	"morgan.slac.stanford.edu" into the .rhosts file on client machine.

-> Question. How do I switch the server of an existing folder from greenjay
	to morgan?
   Answer: 
	First put morgan into CVSROOT, e.g. 
	setenv CVSROOT user@morgan.slac.stanford.edu:/nfs/juno/u5/repo
	then cd to the folder and type 'fixcvs'. Fixcvs can be used to
	change the repository or server information of an existing folder.
