# Scheme Requests for Implementation

The "Scheme Requests for Implementation" (SRFI) process is a new approach to helping Scheme users to write portable and yet useful code. It is a forum for people interested in coordinating libraries and other additions to the Scheme language between implementations.

This manual includes the original documentation of all the SRFIs already ported to PLT Scheme. For more information on the SRFI process, please follow this link.
