This Dumb Interpretively Executed String Expression Language is the kernel of a macro language you can customize by adding C code and embedding it into your program.

It is short, written in portable C, and is readily integrated into any program. It is useful primarily for programs that need a very rudimentary macro expansion facility without the complexity of a full language such as Lisp or FORTH.
