   3 # Add new files to the repository
   4 # Copyright (c) Petr Baudis, 2005
   5 #
   6 # Takes a list of file names at the command line, and schedules them
   7 # for addition to the GIT repository at the next commit. Those files
   8 # are denoted by 'A' in the `cg-status` list. You can add `cg-rm`oved
   9 # files to undo the removal (use `cg-restore` if the file is already
  10 # deleted from the working copy as well); you can undo additions in
  11 # an analogous way using `cg-rm`.
  12 #
  13 # The command will fail if one of the given files does not exist.
  14 #
  15 # Note that directories never have to be added to the repository, and are
  16 # not tracked on their own. That means, you cannot currently add an empty
  17 # directory to 'Cogito'. The reason for this is that 'Cogito' manages
  18 # content and empty directories have no content. Directories are added
  19 # automatically when adding files inside them, or you can add all files in
  20 # a directory using cg-add -r.
  21 #
  22 # OPTIONS
  23 # -------
  24 # -a::  Add all untracked files
  25 #       Add all files in the repository that are currently untracked. Useful
  26 #       when there were some random files added/removed (e.g. by some
  27 #       third-party application) and you want to get the repository in sync:
  28 #       just use `cg-rm -a && cg-add -a`. Note that contrary to `cg-add -r .`,
  29 #       this will not re-add `cg-rm`oved files.
  30 #
  31 # -N::  Only update the lowlevel cache file
  32 #       Only update the cache: do not copy the data into the object database.
  33 #       This is for special purposes when you might not actually _have_ any
  34 #       object database. This option is normally not interesting.
  35 #
  36 # -r::  Add files recursively
  37 #       If you pass cg-add this flag and any directory names, it will try
  38 #       to add files in those directories recursively (with regard to your
  39 #       ignore rules - see `cg-status` for a more detailed description of
  40 #       those). See also above for more notes about cg-add vs. directories.
