Will Richey 63d356ffce 'repo status --orphans' shows non-repo files
'repo status --orphans' searches for non-repo objects
(not within a project), which is particularly helpful
before removing a working tree.

helpDescription = """
'%prog' compares the working tree to the staging area (aka index),
and the most recent commit on this branch (HEAD), in each project
specified. A summary is displayed, one line per file where there
is a difference between these three states.
The -j/--jobs option can be used to run multiple status queries
in parallel.
The -o/--orphans option can be used to show objects that are in
the working directory, but not associated with a repo project.
This includes unmanaged top-level files and directories, but also
includes deeper items. For example, if dir/subdir/proj1 and
dir/subdir/proj2 are repo projects, dir/subdir/proj3 will be shown
if it is not known to repo.
Status Display
--------------
The status display is organized into three columns of information,
for example if the file 'subcmds/status.py' is modified in the
project 'repo' on branch 'devwork':
project repo/ branch devwork
-m subcmds/status.py
The first column explains how the staging area (index) differs from
the last commit (HEAD). Its values are always displayed in upper
case and have the following meanings:
-: no difference
A: added (not in HEAD, in index )
M: modified ( in HEAD, in index, different content )
D: deleted ( in HEAD, not in index )
R: renamed (not in HEAD, in index, path changed )
C: copied (not in HEAD, in index, copied from another)
T: mode changed ( in HEAD, in index, same content )
U: unmerged; conflict resolution required
The second column explains how the working directory differs from
the index. Its values are always displayed in lower case and have
the following meanings:
-: new / unknown (not in index, in work tree )
m: modified ( in index, in work tree, modified )
d: deleted ( in index, not in work tree )
