[p4] What is a Shelf

[David Cooper]

William thinks correctly. I perhaps shouldn't have used the
word "sync". The P4 sync concept did not exist on the system
I was using. For our main use, which was checking multi-platform
builds, it was sufficient just to get hold of the same set of
changes and use them to check all builds before committing.

In this system, a client could "save" a changelist in a "staging" area
on the server, and other clients could pull those changes, overwriting
(and optionally saving) their copies of the files, so that their 
previous state
could be restored easily. Resolving was not an option. The "save" option
was also used as a backup facility for pending changes.
