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