+<h1>Cleaning up the toybox code.</h1>
+
+<p><a href=http://landley.net/notes.html#31-03-2013>Toybox
+hasn't always taken proper advantage of external contributions</a>.
+Lots of people want to help, but their contributions languish out of tree
+or in the "pending" directory, awaiting cleanup.</p>
+
+<p>Toybox's design goals require simpler, tighter, and more explicit code
+than most other implementations, among other reasons to allow better security
+auditing. Writing "another" implementation of standard command line tools
+isn't very interesting, they should be _better_ implementations.
+Unfortunately, this means existing, working commands often take more effort to
+clean up to Toybox's standards than writing a new one from scratch, not
+because they don't work, but because we require an unusual level of polish.</p>
+
+<p>In hopes of teaching more people how to do this
+cleanup work, I've started breaking cleanup changes into smaller chunks and
+posting explanations of each change to the mailing list.
+Below are indexes of each cleanup series. Line/byte totals of completed
+series are given for scale, but the point of this work is simplicity, not
+size.</p>
+
+<p>(Note: mercurial's web viewer doesn't follow renames, so the commit list
+links may not show the final version of each file moved from the "pending"
+directory to its final location. The summaries link the initial and cleaned
+versions of each file when giving line counts.)</p>

+
+<p><a href=http://lists.landley.net/pipermail/toybox-landley.net/2013-April/000893.html>Rationale for removing debug code</a>, the interesting bit says:</p>
+<blockquote><p>Rule of thumb: other people's debugging printfs are seldom as
+useful as your own debugging printfs. Because you know what your output
+_means_, and if you can't annotate the code to dump what you need you haven't
+read enough of it yet.

+<a href=http:/hg/toybox/log/900/toys/pending/uudecode.c>uudecode</a>
+</h1>
+
+<p>This is an example of cleaning up something
+that started in a condition most projects would be quite happy with.
+The initial submission of uuencode and uudecode was a good high
+quality contribution, written by a seasoned developer who did an excellent
+job. It was still possible to shrink uuencode almost by half:</p>
