- _R_l_e_p_a_t_c_h puts smaller RLE files on top of a larger RLE
- image. One use for rlepatch is to place small "fix" images
- on top of a larger image that took a long time to compute.
- Along with _r_e_p_o_s(1), _r_l_e_p_a_t_c_h can also be used as a simple
- way to build image mosaics.
-
- Unlike _r_l_e_c_o_m_p(1), _r_l_e_p_a_t_c_h does not perform any arithmetic
- on the pixels. If the patch images overlap, the patches
- specified last cover those specified first.
-
- If the input files each contain multiple images, they are
- treated as streams of images merging to form a stream of
- output images. I.e., the _nth image in each input file
- becomes part of the _nth image in the output file. The
- process ceases as soon as any input file reaches its end.

- The background image will be read from this file. If
- input is to be taken from stdin, "-" must be specified
- here.

- If specified, output will be written to this file,
- otherwise it will go to stdout.

- _R_l_e_p_a_t_c_h uses the "row" interface to the RLE library. It
- would run much faster using the "raw" interface,
- particularly for placing small patches over a large image.
- Even fixing it to work like _r_l_e_c_o_m_p (which uses "raw" mode
- only for non-overlapping images) would make a major
- improvement.
