+######################################################################
+# NOTES:
+
+# Usage: lsix [ FILES ... ]
+
+# * FILES can be any image file that ImageMagick can handle.
+#
+# * If no FILES are specified the most common file extensions are tried.
+#   (For now, lsix only searches the current working directory.)
+#
+# * Non-bitmap graphics often work fine (.svg, .eps, .pdf, .xcf).
+#
+# * Files containing multiple images (e.g., animated GIFs) will show
+#   all the images if the filename is specified at the command line.
+#   Only the first frame will be shown if "lsix" is called with no
+#   arguments.
+#
+# * Because this uses escape sequences, it works seamlessly through ssh.
+#
+# * If your terminal supports reporting the background and foreground
+#   color, lsix will use those for the montage background and text fill.
+#
+# * If your terminal supports changing the number of color registers
+#   to improve the picture quality, lsix will do so.
+
+# * Only software needed is ImageMagick (e.g., apt-get install imagemagick).
+
+# Your terminal must support SIXEL graphics. E.g.,
+#
+#     xterm -ti vt340
+
+# * To make vt340 be the default xterm type, set this in .Xresources:
+#
+#     ! Allow sixel graphics. (Try: "convert -colors 16 foo.jpg sixel:-").
+#     xterm*decTerminalID	:	vt340
+
+# * Xterm does not support reporting the screen size in pixels unless
+#   you add this to your .Xresources:
+#
+#     ! Allow xterm to read the terminal window size (op #14)
+#     xterm*allowWindowOps      : False
+#     xterm*disallowedWindowOps : 1,2,3,4,5,6,7,8,9,11,13,18,19,20,21,GetSelection,SetSelection,SetWinLines,SetXprop
+
+# * Be cautious using lsix on videos (lsix *.avi) as ImageMagick will
+#   try to make a montage of every single frame and likely exhaust
+#   your memory and/or your patience.
+
+# BUGS
+
+# * Sort order is a bit strange.
+# * ImageMagick's Montage doesn't handle long filenames nicely.
+# * Some transparent images (many .eps files) presume a white background
+#   and will not show up if your terminal's background is black.
+# * This file is getting awfully long for a one line kludge. :-)
+
+# LICENSE INFORMATION
+# (AKA, You know your kludge has gotten out of hand when...)
+
+# Dual license:
+# * You have all the freedoms permitted to you under the
+#   GNU GPL >=3. (See the included LICENSE file).
+
+# * Additionally, this program can be used under the terms of whatever
+#   license 'xterm' is using (now or in the future). This is primarily
+#   so that, if the xterm maintainer (currently Thomas E. Dickey) so
+#   wishes, this program may be included with xterm as a Sixel test.
+#   However, anyone who wishes to take advantage of this is free to do so.
