Display a changelist description
Display a changelist description, including the changelist number, user, client, date of submission, textual description, list of affected files and diffs of files updated. Pending changelists are flagged as 'pending' and the list of affected files and file diffs is not displayed.
The -d<flag> passes a flag to the built-in diff routine to modify the output: -dn (RCS), -dc (context), -du (unified).
The -s flag requests a shortened form of describe that doesn't include the diffs of files updated.
