def description
  <<-EOF
Apply a patch directly to the work tree.  This command is a building block used
by other, more powerful commands and most users will never need to invoke it
directly.

The --depth option specifies how many directories deep to recursively attempt
to apply the patch in.  For a depth of 2, the patch will be attempted in the
repositority root, foo, foo/bar, but not foo/bar/baz.  It will also try
stripping off up to 2 directories off of the paths inside the patch, the same
as -p0, -p1, and -p2 with patch(1).  The option is ignored if the patch appears
to have been generated with git.  The default value is 0, but this can be
changed with the trac.depth configuration option.

If the patch fails to apply even after a depth search, and the patch contains
carriage returns, a second pass is made with those carriage returns stripped.

If no argument is given, the patch is read from stdin.
  EOF
