The SDL is an open source multimedia toolkit being developed under the GNU Lesser General Public License (LGPL). It is an attempt to create an open source library that provides functionality similar to Microsoft's DirectX APIs for Win32. There are currently versions of SDL under development for Linux, Win32, and BeOS. Unofficial ports and proposed platforms include Solaris, IRIX, FreeBSD, and MacOS.

The author is Sam Lantinga who is the lead programmer for Loki Entertainment Software. SDL is based upon some of his experience in porting games to Linux for them.
