errr... Sort of. But this confuses me as well. What I have done is attached all
3
postings from the  CCIUG and apologies to David 'cuz I think he's probably

the protocol actually works.

If your VOB storage directory is /ccstore/projectb/src.vbs then cleartext pool
is in the c/cdft subdirectory, the source pool is in the s/sdft subdirectory
and the derived object pool is in the d/ddft subdirectory (by default).

ClearCase International User Group cciug at rational.com
but you need a user account to access it and the archives :-(
