This is a short summary of code metrics showing how lynx has grown from
release to release.  It also shows how the original codebase has
been almost completely replaced by contributors after the release of
lynx 2.4.2 in 1996.  The numbers shown are for lines of text, to keep
the presentation simple.

Beginning with 2.8.6, the percentage of the remaining original codebase is
shown on two lines (i.e., comparing against 2.4.2 indented to use the current
coding style, or using only the original source).  Comparisons using the
original source give lower estimates of untouched code, though either must be
viewed taking into account insignificant similarities (such as blank lines).

Starting in 2.8.6dev.3, all C source code has been routinely indented using
the lnx-indent script from
    https://invisible-island.net/cindent/

Current lynx releases contain a large amount of text other than C code.
That includes plain text, html, message libraries, custom and generated
scripts.

Older attributions are problematic for several reasons:
  + some contributors were not credited,
  + some changes were not recorded,
  + the level of importance of changes in the older logs differs noticeably
    from the newer logs.
There is neither a source repository nor a mailing-list archive to consult to
resolve these issues.

However, some information can be gleaned from the existing change-logs
to show the principal contributors for each release (i.e., not listing those
with less than 1%):
