    longDescription = ''

      s7 is a Scheme interpreter intended as an extension language for other

      applications.

      Although it is a descendant of tinyScheme, s7 is closest as a Scheme

      dialect to Guile 1.8. It is expected to be compatible with r5rs and r7rs.

      It has continuations, ratios, complex numbers, macros, keywords,

      hash-tables, multiprecision arithmetic, generalized `set!`, unicode, and so

      on. It does not have `syntax-rules` or any of its friends, and it thinks

      there is no such thing as an inexact integer.

      s7 is an extension language of Snd and sndlib, Rick Taube's Common Music

      (commonmusic at sourceforge), Kjetil Matheussen's Radium music editor, and

      Iain Duncan's Scheme for Max (or Pd).
