# 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.

SDL: SDL (Simple DirectMedia Layer library)
SDL:
SDL: This is the Simple DirectMedia Layer, a generic API that provides low
SDL: level access to audio, keyboard, mouse, joystick, 3D hardware via
SDL: OpenGL, and 2D framebuffer across multiple platforms.
SDL:
SDL: SDL links against alsa-lib, arts, audiofile, esound, and the X11
SDL: libraries.  Make sure all of these are installed if you're planning to
SDL: use SDL (a full installation will cover all of the prerequisites).
