Author: brooks

New Revision: 324619
URL: https://svnweb.freebsd.org/changeset/base/324619
Log:
Switch procstat from subcommand flags to verbs
- Use an enumerated value instead of separate flags for commands
- Look for a verb if no command flag is set
- Lookup the "xocontainer" value based on the command
- Document the new command verbs in the man-page
