   6 # Takes a list of file names at the command line, and schedules them
   7 # for removal from the GIT repository at the next commit. Those files
   8 # are denoted by 'D' in the `cg-status` list. You can remove `cg-add`ed
   9 # files to undo the addition; you can undo removals in an analogous way
  10 # using `cg-add` and restore files deleted from the working copy using
  11 # `cg-restore`.
  12 #
  13 # OPTIONS
  14 # -------
  15 # -a:: Remove all files which are gone from the working copy
  16 #       Record removal of all files which have been deleted from
  17 #       the working copy. Useful when there were some random files
  18 #       added/removed (e.g. by some third-party application) and you
  19 #       want to get the repository in sync: just use
  20 #       `cg-rm -a && cg-add -a`.
  21 #
  22 # -f:: Force removal of the physical files
  23 #       Also delete the files from the tree physically.
  24 #
  25 # -n:: Keep the physical files
  26 #       Do not delete the files from the tree physically, if they are
  27 #       still there. So it effectively just makes Cogito to stop caring
  28 #       about the file. This is the default.
  29 #
  30 # -r:: Remove files recursively
  31 #       If you pass cg-rm this flag and any directory names, it will try
  32 #       to remove files in those directories recursively.
  33
  34 # Testsuite: Partial (used in many tests but a dedicated testsuite is missing)
