Simple DirectMedia Layer \(libSDL\) is a cross-platform multimedia library designed to provide low level access to audio, keyboard, mouse, joystick, 3D hardware via OpenGL, and 2D video framebuffer. It is used by MPEG playback software, emulators, and many popular games, including the award winning Linux port of "Civilization: Call To Power."

Allows definition of macros which include expander-definition forms, like match expanders

Provides qualified-in, a require form which prefixes its subforms with their module names and a `:`.

PLplot is a cross-platform software package for creating scientific plots whose (UTF-8) plot symbols and text are limited in practice only by what Unicode-aware system fonts are installed on a user's computer. The PLplot software, which is primarily licensed under the LGPL, has a clean architecture that is organized as a core C library, separate language bindings for that library, and separate device drivers that are dynamically loaded by the core library which control how the plots are presented in noninteractive and interactive plotting contexts.
