/*
* Normally, the procedures that implement PostScript operators (named zX
* where X is the name of the operator, e.g., zadd) are private to the
* file in which they are defined. There are, however, a surprising
* number of these procedures that are used from other files.
* This file, opextern.h, declares all z* procedures that are
* - referenced from outside their defining file, and
* - present in *all* configurations of the interpreter.
* For z* procedures referenced from outside their file but not present
* in all configurations (e.g., Level 2 operators), the file making the
* reference must include a local extern. Not pretty, but c'est la vie.
