libsdl1.2-compat-dev - 1.2.68-3 main

sdl12-compat provides a binary compatible API for programs built
against SDL 1.2, but using SDL 2.0.
.
If you are writing new code, please target SDL 2.0 directly instead
of using this layer.
.
This transitional package depends on a version of libsdl1.2-dev
new enough that it actually contains sdl12-compat development files.
