The site is set up like this:

<pre>

	autohandler
	config
	index.html
	abc-src/
		*.abc (the source abc files)
	abc/
		dhandler
	pdf/
		dhandler
	jpg/
		dhandler
	midi/
		dhandler

</pre>
<p>
To add new .abc files, just drop them into the abc-src/ directory, everything else
takes care of itself.
<p>
Requests to urls for abc/, pdf/, jpg/ or midi/ are handled by the dhandler in 
that directory which takes care of generating the requested file and caching
it for future use.
<p>
The output is generated using subshells and temp files.  I'd rather use pipes than tempfiles
but not all the utilities are fully pipeable, and I wasn't able to find a good solution
using two-way pipes and/or forking under mod_perl.  I'm open to suggestions.  
<p>
If you're curious, the commands used to generate the output looks like this:
<p>

<pre>
jpg:
    | abcm2ps - -O- 2>/dev/null | gs -sDEVICE=jpeg -sOutputFile=$tempfilename -q - -c quit 

midi:
    | abc2midi - -o $tempdir/output.mid

pdf:
    | abcm2ps - -O- 2>/dev/null | gs -sDEVICE=pdfwrite -sOutputFile=$tempfilename -q - -c quit
</pre>
