Add "<!-- BEFORE: 1st line of markdown file: FILE/PATH -->" before the markdown content. This line appears in the generated HTML. Add "<!-- AFTER: last line of markdown file: FILE/PATH -->" after the markdown content. This line appears in the generated HTML. We test a fix relating to problems produced by `pandoc(1)` when footnotes are added at the end of generated HTML. This test is made for `2000/bmeyer/index.html`. Fixed exit 4 in `bin/md2html.sh that should be exit 5. Changed `bin/md2html.sh` VERSION from to "1.3 2024-04-14" to "1.4 2024-04-18". Run `bin/readme2index.sh -v 1 2000/bmeyer` to perform the above.

<p>If you are still confused and want to read a spoiler, check out

the source and it will be clear as mud!</p>
|
||
<p>And for a misleading hint, consider who won! :-)</p>
|

<p>And if you really can’t see what is going on, here is an extra spoiler:</p>
|

<pre><code> ./huffman < huffman.c 2>/dev/null</code></pre>
|
||
<p>This entry was very well received at the IOCCC BOF.</p>
|
||
<h2 id="authors-remarks">Author’s remarks:</h2>
|
||
<p>This filter program is really not obfuscated code. It compiles cleanly
|
||
with an ANSI C compiler and comes with user documentation that even a
|
||
blind person could read.</p>
|
||
<p>The program is a bidirectional filter with the output of the program
|
||
suitable for its input. The output of this program, when used as input,
|
||
undoes the original program filtering.</p>
|
||
<p>This program accepts any alphanumeric text that has lines less than 100
|
||
characters. The user is encouraged to use the program’s source as input
|
||
to the executable.</p>
|
||
<p>This program is best appreciated on a tactile monitor.</p>
