7.4.13 SRFI

(require 'srfi)

Implements Scheme Request For Implementation (SRFI) as described at http://srfi.schemers.org/

Macro: cond-expand <clause1> <clause2> …

Syntax: Each <clause> should be of the form

(<feature> <expression1> …)

where <feature> is a boolean expression composed of symbols and ‘and’, ‘or’, and ‘not’ of boolean expressions. The last <clause> may be an “else clause,” which has the form

(else <expression1> <expression2> …).

The first clause whose feature expression is satisfied is expanded. If no feature expression is satisfied and there is no else clause, an error is signaled.

SLIB cond-expand is an extension of SRFI-0, http://srfi.schemers.org/srfi-0/srfi-0.html.
