The notion of Little Languages was introduced by Jon Bentley in his discussion of Kernighan's and Cherry's eqn -- a troff preprocessor for typesetting mathematics. Both papers are reprinted at the beginning of the Volume. They are followed by an essay by Paul Hudak on Domain Specific Languages. The remainder of the volume features languages and tools that every programmer needs to use: -- troff and its pre-processors by Jaap Akkerhuis-- AWK and sed by Arnold Robbins-- SQL by David Klappholz-- Tcl/Tk by Cameron Laird and Kathy Soraiz-- Perl by Hal Pomeranz-- Python by Mark Lutz-- Little Languages for Music by Peter S. Langston.
