About iconx

From Debian's package description

Ideal for both complex nonnumerical applications and for situations where users need quick solutions with a minimum of programming effort, Icon is a high-level, general purpose programming language with a syntax similar to Pascal and C. Its applications include: rapid prototyping, analyzing natural languages, generating computer programs, and artificial intelligence. (From the back cover of the book "The Icon Programming Language," by Griswold and Griswold.)

This package contains the Icon executor, iconx, which is needed to execute interpreted Icon programs. If you are starting from Icon source code (as opposed to precompiled `ucode' files), you will also need the icont package, which converts your Icon source into a program that iconx can execute.

From Debian's description of the iconx package, under that package's license.
