The files in this directory are the examples from the Adobe "Blue Book":

    "PostScript Language Tutorial and Cookbook"
    Adobe Systems Incorporated

They have been modified slightly to make them fit better onto the screen
and to add atouch of colour.

Before you run any of these programs, type:

    (examples/init.ps) run

If you are viewing the output on the screen you may want to pause after
each page:

    showwait

To run a single program

    (examples/blue/prog...ps) runsave

To run them all:

    (examples/blue/all.ps) runsave

N.B. You need to be in the parent directory of the examples for this to
work!
