This library is intended for developers who wish to manipulate (read, parse, modify, and create) symbolic expressions from C or C++ programs. A symbolic expression, or s-expression, is essentially a LISP-like expression such as (a (b c)). S-expressions are able to represent complex, structured data without requiring additional meta-data describing the structure. They are recursively defined: an s-expression is a list of either atoms or s-expressions. In the example above, the expression contains an atom "a" and an s-expression, which in turn contains two atoms, "b" and "c". They are simple, useful, and well understood.
