Remove hint.html and index.html
As per discussions on GitHub the index.html and hint.html files should be deleted in favour of README.md files (from any .text/.txt/.markdown/.md files which will be turned into README.md in an upcoming commit).

<h2>Judges' comments:</h2>

|

<h3>To build:</h3>
|
||||
|
||||
<pre><code>make hamano
|
||||
</code></pre>
|
||||
|
||||
<h3>To run:</h3>
|
||||
|
||||
<pre><code>./hamano < textfile > output.pdf
|
||||
</code></pre>
|
||||
|
||||
<h3>Try:</h3>
|
||||
|
||||
<pre><code>./hamano < hint.text > hint.pdf
|
||||
|
||||
# You can read output.pdf with PDF reader
|
||||
acroread hint.pdf
|
||||
# or
|
||||
evince hint.pdf
|
||||
|
||||
# deobfuscate
|
||||
gcc -xc hint.pdf -o hint
|
||||
./hint
|
||||
|
||||
# Of course, You can obfuscate c code
|
||||
echo 'void main(){puts("Hello World!");}' | ./hamano > hello.pdf
|

gcc -xc hello.pdf -o hello2
|

./hello2 | gcc -xc - -o ./hello3

<h3>Selected Judges Remarks:</h3>
|
||||
|
||||
<p>This entry treads into a new territory for IOCCC - generating PDF files.</p>
|
||||
|
||||
<p>The originally submitted entry could have been thought of as a “Best abuse of
|
||||
Ghostscript” winner. :-)</p>
|
||||
|
||||
<p>The source code and rendered pages are obfuscated for humans (where
|
||||
is the font?), and the submitted entry created PDF files that left Ghostscript
|
||||
confused.</p>
|
||||
|
||||
<p>The results can be viewed with Acrobat Reader,
|
||||
<a href="http://en.wikipedia.org/wiki/Evince">evince</a> and Apple’s Preview.</p>
|
||||
|
||||
<p>The updated version can also be viewed using Ghostscript.</p>
|
||||
|
||||
<p>There is something strange about the little flags in the output.
|
||||
A search of English literature will provide a hint. The conclusion
|
||||
you might draw is too elementary. :-)</p>
|
||||
|
||||
<p>So what do those flags really mean?</p>
|
||||
|
||||
<p>The [Dancing men algorithm][1] might be useful.</p>
|
||||
|
||||
<p>Don’t forget to take a look at the generated PDF, perhaps you might even want
|
||||
to compile the output with a C compiler. When you run it, what does it
|
||||
output?</p>
|
||||
|
||||
<h2>Author’s comments:</h2>
|
||||
|
||||
<p>This program obfuscate text file into PDF file with Dancing men
|
||||
algorithm.</p>
|
||||
|
||||
<p><a href="http://en.wikipedia.org/wiki/The_Adventure_of_the_Dancing_Men">http://en.wikipedia.org/wiki/The_Adventure_of_the_Dancing_Men</a></p>
|
||||
|
||||
<p>Probably, the output PDF file is compliant with PDF 1.3. And also
|
||||
available to compile as C code.</p>
|
||||
|
||||
<p>I’ve been tested with GCC 4.7 and Clang 3.0 on Linux, and following
|
||||
PDF Reader:</p>
|
||||
|
||||
<ul>
|
||||
<li>Adobe Acrobat Reader</li>
|
||||
<li>Evince</li>
|
||||
<li>Ghostscript</li>
|
||||
<li>Xpdf</li>
|
||||
</ul>
|
||||
|
||||
|
||||
<h3>Obfuscations</h3>
|
||||
|
||||
<p>This program is obfuscated by using classical methods.
|
||||
But can you find out the embedded font from fragmented glyph?</p>
