  4== Included modules

  6The CHICKEN system comes shipped with several modules.  This section
  7of the manual provides a reference guide to all the modules that are
  8part of a standard installation.  On top of these, you can install
  9additional modules through the [[Extensions|eggs]] system.
 10
 11Note that toplevel code that is not contained in a module has by
 12default all exports of the [[Module scheme|scheme]], 
 13[[Module (chicken base)|(chicken base)]] and 
 14[[Module (chicken syntax)|(chicken syntax)]]  available.

 80In addition to the core modules listed above, the following SRFI modules can be
 81imported. These provide access to identifiers described by the SRFI, but which
 82may already be defined by other parts of CHICKEN's standard library.

 96
 97Other SRFI features may be supported but do not correspond to any importable module.
