(description
"Microscheme, or @code{(ms)} for short, is a functional programming
language for the Arduino, and for Atmel 8-bit AVR microcontrollers in general.
Microscheme is a subset of Scheme, in the sense that every valid @code{(ms)}
program is also a valid Scheme program (with the exception of Arduino
hardware-specific primitives). The @code{(ms)} compiler performs function
inlining, and features an aggressive tree-shaker, eliminating unused top-level
definitions. Microscheme has a robust @dfn{Foreign Function Interface} (FFI)
meaning that C code may be invoked directly from (ms) programs.")
