As discussed in the August 13, 2025 external meeting this PR adds some new entries to the Glossary page: Break package, Briefing Blurb, Display, and Package. It also links to the Jargon File.

Add to the glossary the entries Break package, Briefing Blurb, Display, and Package. Link to the Jargon File.

: The Interlisp subsystem that comprises the debugger (also known as break window) and other debugging facilities. Named after the `BREAK` function and breakpoints.

Briefing Blurb
: Any one of the technical reports in a series that introduced Xerox PARC newcomers to the computing and network environment at the Computer Science Laboratory. Written in an upbeat style, their titles followed a pattern that included the expression "Briefing Blurb" such as *The Alto-Dolphin-Dorado Briefing Blurb: Exploring the Ethernet with Mouse and Keyboard* and *The Briefing Blurb: Exploring the Ethernet with Mouse and Keyboard*.

The PARC use of "briefing blurb" was indeed brief (a "blurb") and meant to "brief" a newcomer to the parc milieu, but it wasn't a "technical report" (which is something you might make at the end of a project or significant milestone). It contained folklore, use patterns, usage notes, etc. of various computing environments. Typically the idea was to assign a newcomer to the group to update the group's briefing blurb. This insured that it was frequently updated and also the task of updating was also educational.

What about "Any one of the internal documents in a series that introduced Xerox PARC newcomers..."?

I'll go with this.

## Vocabulary and relationships

I'm not sure "(unsuccessful)" captures the status of AltoLisp. It was an initial foray into building a microcoded Lisp implementation following Peter Deutch's paper on compact Lisp programs. AltoLisp was the basis for DoradoLisp with new microcode. AltoLisp failed because the "working set" for a "demand paged" Lisp system was bigger than the amount of memory available on the Alto.

AltoLisp is actually a preexisting entry not in this PR but I can of course change it to "An attempt to build a microcoded Lisp-based OS for running Interlisp on an Alto", "An experimental microcoded implementation of a Lisp-based OS for running Interlisp on an Alto", or something else.

"An experimental microcoded implementation of Interlisp on an Alto personal computer."

I'll go with your suggestion too.

Fuji Xerox. Subsequently ported to little-endian processors and other operating systems.

Package
: An Interlisp subsystem such as the break package (q.v.) or the window package (window system). Not to be confused with Common Lisp packages or packaged applications.

How about leading with the ambiguity:

The term Package has several different meanings depending on the context:

  • Informally, a collection of utilities or submodule in Interlisp (the "break package" and the "file package")
  • A feature of Commmon Lisp symbol support; the package system allows the combining of Interlisp symbols (written with "IL:" prefix) and Common Lisp symbols (written with a "lisp:" prefix).

There is no 'window package' so pick another example.

Okay thanks I'll pick your version.

I heard Richard Burton mention the window package in a recent meeting and assumed the expression was more widely used.

The IRM mentions:

  • file package
  • "the WHEREIS library package"
  • '"library" packages'
  • record package
  • DWIM package
  • network packages
    etc.
