annotate ProcessManager.py @ 4:f64af329930f

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Any user can now use ProcessManager to manage processes--root is no longer required. However, an error will be displayed if the user doesn't have privileges to manage a process because a user/group change is required.
