+acidwarp (display geometric images and rotate the palette)
+
+Acid Warp is an eye-candy program. Run it and watch the pretty
+colors. Each picture is the graphic representation of a mathematical
+function.
+
+There is no man page. Run 'acidwarp -h' for a list of command-line
+options, and see the docs in /usr/doc/acidwarp-$VERSION for a list
+of keyboard commands. It's worth mentioning here that the keystroke
+to exit is Control-Break, and that double-clicking in the window will
+toggle windowed vs. fullscreen.
+
+Build options:
+
+By default, acidwarp is built with SDL-2.0 and OpenGL. To disable
+OpenGL, set GL=no in the script's environment.
+
+To build with SDL-1.2, set SDL2=no. This will also disable OpenGL,
+since acidwarp doesn't support building with SDL-1.2 and OpenGL.
+Building with SDL-1.2 actually has a use-case: it will allow "acidwarp
+-f -k" to span multiple screens, if you have them (the SDL-2.0 build
+only runs fullscreen on one monitor).

+# HOW TO EDIT THIS FILE:
+# 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
+# customary to leave one space after the ':' except on otherwise blank lines.
