+Notes:
+
+snapscreenshot is *fast*, when compared to fbdump and fbcat. However,
+the reason it's so fast is that it doesn't read the graphic content of
+the framebuffer. Instead, the text content of the screen is read (from
+the /dev/vcs* devices) and rendered in the current console font... which
+is the current font of the console you executed snapscreenshot from,
+*not* the font in the console you're taking a snapshot of!
+
+Also, custom fonts just don't work well with snapscreenshot. Depending
+on the font, you may get an error (GIO_FONTX), a segmentation fault,
+or else the resulting screenshot is garbled.
+
+Because /dev/vcs* is used, snapscreenshot does NOT work for taking
+screenshots of software that actually uses the framebuffer for graphics,
+e.g. fbpdf, feh, "mplayer -vo fbdev", "links -g -driver fb". For these,
+use fbcat or fbdump instead.
+
+By default, the text on all the consoles ends up in the output image. To
+take a shot of only one console, use a command like:
+
+# snapscreenshot --firstwin 1 -c1 -x1 > shot.tga
+
+...or use this:
+
+# snapscreenshot.cur > shot.tgz
+
+The snapscreenshot.cur script was written by the SlackBuild author,
+and is not part of snapscreenshot itself.

+snapscreenshot (screenshot program for text consoles)
+
+snapscreenshot creates a .tga (Targa) image file from the text contents
+of the Linux framebuffer consoles (by default, all of the consoles,
+tiled in a single image).
+
+This probably doesn't work for non-framebuffer consoles (not tested).
+
+By default, snapscreenshot is installed setuid root and executable by
+users in the 'video' group. Normally on Slackware, users logged in at
+the console are in the 'video' group by default. If you don't like this,
+export SETUID=no in the script's environment. This will require root
+access (e.g. su or sudo) for snapscreenshot to work.
+
+See NOTES.txt for more information.

+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
