define Package/chicken-scheme/description/Default
  Chicken is an implementation of the Scheme language. It is portable,
  efficient, and supports the R5RS and R7RS (work in progress) standards, and
  many extensions.
  Chicken can be used as a scripting language to automate tasks.
  For more information, please refer to the Chicken Scheme website at
  https://call-cc.org.

define Package/chicken-scheme-interpreter/description
$(call Package/chicken-scheme/description/Default)
  This package contains the interpreter, 'csi', only -- the compiler and the
  package installer are not included because they depend on a C compiler.

define Package/chicken-scheme-full/description
$(call Package/chicken-scheme/description/Default)
  This package contains the interpreter, 'csi'; the compiler, 'csc'; the tools
  for installing and removing eggs (modules); the profiler and the debugger.
  Note that this package depends on gcc, which is quite large (more than 100Mb).
