-Thank you for your response about indent. I was wrong in my original
-observation (or mis-observation :-). UCB did keep the Illinois
-copyright intact.
-
-The issue still is whether we can distribute indent, and if we can, which
-version. David Willcox (the author) states that:
-
-| Several people have asked me on what basis I claim that indent is in
-| the public domain.  I knew I would be sorry I made that posting.
-| 
-| Some history.  Way back in 1976, the project I worked on at the
-| University of Illinois Center for Advanced Computation had a huge
-| battle about how to format C code.  After about a week of fighting, I
-| got disgusted and wrote a program, which I called indent, to reformat C
-| code.  It had a bunch of different options that would let you format
-| the output the way you liked.  In particular, all of the different
-| formats being championed were supported.
-| 
-| It was my first big C program.  It was ugly.  It wasn't designed, it
-| just sort of grew.  But it pretty much worked, and it stopped most of
-| the fighting.
-| 
-| As a matter of form, I included a University of Illinois Copyright
-| notice.  However, my understanding was that, since the work was done
-| on an ARPA contract, it was in the public domain.
-| 
-| Time passed.  Some years later, indent showed up on one of the early
-| emacs distributions.
-| 
-| Later still, someone from UC Berkeley called the UofI and asked if
-| indent was in the public domain.  They wanted to include it in their
-| UNIX distributions, along with the emacs stuff.  I was no longer at the
-| UofI, but Rob Kolstad, who was, asked me about it.  I told him I didn't
-| care if they used it, and since then it has been on the BSD distributions.
-| 
-| Somewhere along the way, several other unnamed people have had their
-| hands in it.  It was converted to understand version 7 C.  (The
-| original was version 6.)  It was converted from its original filter
-| interface to its current "blow away the user's file" interface.
-| The $HOME/.indent.pro file parsing was added.  Some more formatting
-| options were added.
-| 
-| The source I have right now has two copyright notices.  One is the
-| original from the UofI.  One is from Berkeley.
-| 
-| I am not a lawyer, and I certainly do not understand copyright law.  As
-| far as I am concerned, the bulk of this program, everything covered by
-| the UofI copyright, is in the public domain, and worth every penny.
-| Berkeley's copyright probably should only cover their changes, and I
-| don't know their feelings about sending it out.  
-
-In any case, there appears to be none at UofI to clarify/and change
-that copyright, but I am confident (based on the statements of its
-author) that the code, as it stands with its copyright, is
-distributable, and will not cause any legal problems.
-
-Hence, the issue reduces to *which* one to distribute through
-comp.sources.unix. I would suggest that with the permission of you
-folks (given that you have parts copyrighted), we distribute the 4.3
-version of indent, which appears to be the most up-to-date version. I
-happen to have just about every known version of indent, including the
-very original submission from the author to a unix tape, later the
-G-Emacs version, any 4.n version, sun version and the Unipress
-version.  I still think we should not have to "go-back-in-time" and
-re-do all the work you people have done.
-
-I hope to hear from you as to what you think about this. You may of
-course send 4.3 version to the moderator directly, or you can let me
-know of your permission, and I will send the sources, or you can let
-me know that 4.3 version is off-limits, in which case we would probably
-have to revert to an older version. One way or another, I hope to get
-a version of indent to comp.sources.unix.
-
-regards..      oz

+# History
+
+This is NetBSD indent.  It originally came from the University of Illinois via
+some distribution tape for PDP-11 Unix.  It has subsequently been hacked upon 
+by James Gosling @ CMU.  At some point in the 1970s or even 1980s, it was 
+thought to be "the nicest C pretty printer around".  Around 1985, further
+additions to provide "Kernel Normal Form" were contributed by the folks at Sun 
+Microsystems.
+
+Between 2000 and 2019, FreeBSD maintained the code, adding several features.
+NetBSD imported these changes on 2019-04.04.
+
+In 2021, indent was updated to handle C99 comments, cleaning up the code.  It
+got a proper test suite, uncovering many inconsistencies and bugs that either
+had been there forever or had been introduced by importing the FreeBSD version
+in 2019.
