21
22 Sven Verdoolaege added the iconv support and the DB3 locking.
23
24 Jun-ichiro itojun Hagino developed the file encoding detection
25 techniques in his nvi-m17n.

30o This software is several years old and is the product of many folks' work.
31
32 This software was originally derived from software contributed to
33 the University of California, Berkeley by Steve Kirkendall, the
34 author of the vi clone elvis. Without his work, this work would
35 have been far more difficult.
36
37 IEEE POSIX 1003.2 style regular expression support is courtesy of
38 Henry Spencer, for which I am *very* grateful.
39
40 Elan Amir did the original 4BSD curses work that made it possible
41 to support a full-screen editor using curses.
42
43 George Neville-Neil added the Tcl interpreter, and the initial
44 interpreter design was his.
45
46 Sven Verdoolaege added the Perl interpreter.
47
48 Rob Mayoff provided the original Cscope support.
49
50o Many, many people suggested enhancements, and provided bug reports and
51 testing, far too many to individually thank.

53o From the original vi acknowledgements, by William Joy and Mark Horton:
54
55 Bruce Englar encouraged the early development of this display
56 editor. Peter Kessler helped bring sanity to version 2's
57 command layout. Bill Joy wrote versions 1 and 2.0 through 2.7,
58 and created the framework that users see in the present editor.
59 Mark Horton added macros and other features and made the editor
60 work on a large number of terminals and Unix systems.
61
62o And...
63 The financial support of UUNET Communications Services is gratefully
64 acknowledged.
