GNU AutoGen - The Automated Program Generator: Common Functions

3.5 Common Scheme Functions

This section describes a number of general purpose functions that make the kind of string processing that AutoGen does a little easier. Unlike the AutoGen specific functions (see AutoGen Functions), these functions are available for direct use during definition load time. The equality test (see SCM =) is “overloaded” to do string equivalence comparisons. If you are looking for inequality, the Scheme/Lisp way of spelling that is, “(not (= ...))”.
