# Acknowledgments for X11R7

This update to the X11 Intrinsics drops support for K&R C, as well as improving its use of Standard C features, notably const.

- Matt Dew did the initial conversion of this specification from nroff to DocBook.

  Later, I expanded on that, improving the formatting, as well as updating the function prototypes in the specification as well as the related manual pages.

- Matthieu Herrb modified the Intrinsics header files to drop support for K&R C, leaving the Standard C prototypes.

  Later, he applied my changes to complete the conversion of the library source from a mixture of K&R C and Standard C to just use the standard language features.

- Others (including Alan Coopersmith, Gaetan Nadon, Walter Harms, and Kevin E. Martin) have worked to maintain the library's build-scripts and documentation.

# Acknowledgments for X11R6

The design of the X11 Intrinsics was done primarily by Joel McCormack of Digital WSL. Major contributions to the design and implementation also were done by Charles Haynes, Mike Chow, and Paul Asente of Digital WSL. Additional contributors to the design and/or implementation were:

Loretta Guarino-Reid (Digital WSL) | Rich Hyde (Digital WSL)
Susan Angebranndt (Digital WSL) | Terry Weissman (Digital WSL)
Mary Larson (Digital UEG) | Mark Manasse (Digital SRC)
Jim Gettys (Digital SRC) | Leo Treggiari (Digital SDT)
Ralph Swick (Project Athena and Digital ERP) | Mark Ackerman (Project Athena)
Ron Newman (Project Athena) | Bob Scheifler (MIT LCS)

The contributors to the X10 toolkit also deserve mention. Although the X11 Intrinsics present an entirely different programming style, they borrow heavily from the implicit and explicit concepts in the X10 toolkit.

The design and implementation of the X10 Intrinsics were done by:

Terry Weissman (Digital WSL)
Smokey Wallace (Digital WSL)
Phil Karlton (Digital WSL)
Charles Haynes (Digital WSL)
Frank Hall (HP)

The design and implementation of the X10 toolkit’s sample widgets were by the above, as well as by:

Ram Rao (Digital UEG)
Mary Larson (Digital UEG)
Mike Gancarz (Digital UEG)
Kathleen Langone (Digital UEG)

These widgets provided a checklist of requirements that we had to address in the X11 Intrinsics.

Thanks go to Al Mento of Digital’s UEG Documentation Group for formatting and generally improving this document and to John Ousterhout of Berkeley for extensively reviewing early drafts of it.

Finally, a special thanks to Mike Chow, whose extensive performance analysis of the X10 toolkit provided the justification to redesign it entirely for X11.

The current design of the Intrinsics has benefited greatly from the input of several dedicated reviewers in the membership of the X Consortium. In addition to those already mentioned, the following individuals have dedicated significant time to suggesting improvements to the Intrinsics:

Steve Pitschke (Stellar) | C. Doug Blewett (AT&T)
Bob Miller (HP) | David Schiferl (Tektronix)
Fred Taft (HP) | Michael Squires (Sequent)
Marcel Meth (AT&T) | Jim Fulton (MIT)
Mike Collins (Digital) | Kerry Kimbrough (Texas Instruments)
Scott McGregor (Digital) | Phil Karlton (Digital)
Julian Payne (ESS) | Jacques Davy (Bull)
Gabriel Beged-Dov (HP) | Glenn Widener (Tektronix)

Thanks go to each of them for the countless hours spent reviewing drafts and code.

From Release 3 to Release 4, several new members joined the design team. We greatly appreciate the thoughtful comments, suggestions, lengthy discussions, and in some cases implementation code contributed by each of the following:

Don Alecci (AT&T) | Ellis Cohen (OSF)
Donna Converse (MIT) | Clive Feather (IXI)
Nayeem Islam (Sun) | Dana Laursen (HP)
Keith Packard (MIT) | Chris Peterson (MIT)
Richard Probst (Sun) | Larry Cable (Sun)

In Release 5, the effort to define the internationalization additions was headed by Bill McMahon of Hewlett Packard and Frank Rojas of IBM. This has been an educational process for many of us, and Bill and Frank’s tutelage has carried us through. Vania Joloboff of the OSF also contributed to the internationalization additions. The implementation efforts of Bill, Gabe Beged-Dov, and especially Donna Converse for this release are also gratefully acknowledged.

The Release 6 Intrinsics is a result of the collaborative efforts of participants in the X Consortium’s intrinsics working group. A few individuals contributed substantial design proposals, participated in lengthy discussions, reviewed final specifications, and in most cases, were also responsible for sections of the implementation. They deserve recognition and thanks for their major contributions:

Paul Asente (Adobe) | Larry Cable (SunSoft)
Ellis Cohen (OSF) | Daniel Dardailler (OSF)
Vania Joloboff (OSF) | Kaleb Keithley (X Consortium)
Courtney Loomis (HP) | Douglas Rand (OSF)
Bob Scheifler (X Consortium) | Ajay Vohra (SunSoft)

Many others analyzed designs, offered useful comments and suggestions, and participated in a significant subset of the process. The following people deserve thanks for their contributions: Andy Bovingdon, Sam Chang, Chris Craig, George Erwin-Grotsky, Keith Edwards, Clive Feather, Stephen Gildea, Dan Heller, Steve Humphrey, David Kaelbling, Jaime Lau, Rob Lembree, Stuart Marks, Beth Mynatt, Tom Paquin, Chris Peterson, Kamesh Ramakrishna, Tom Rodriguez, Jim VanGilder, Will Walker, and Mike Wexler.

I am especially grateful to two of my colleagues: Ralph Swick for expert editorial guidance, and Kaleb Keithley for leadership in the implementation and the specification work.
