## NAME
       projid - the project name mapping file

## DESCRIPTION
       The  _/etc/projid_ file provides a mapping between numeric project identifiers and a simple hu‐
       man readable name (similar relationship to the one that exists between usernames  and  uids).
       Its format is simply:

            # comments are hash-prefixed
            # ...
            cage:10
            logfiles:42


       This  file is optional, if a project identifier cannot be mapped to a name, it will be parsed
       and displayed as a numeric value.
