    longDescription = ''
      CHICKEN is a compiler for the Scheme programming language.
      CHICKEN produces portable and efficient C, supports almost all
      of the R5RS Scheme language standard, and includes many
      enhancements and extensions. CHICKEN runs on Linux, macOS,
      Windows, and many Unix flavours.
