/*
* This is a quick and dirty HTTP server that uses PhysicsFS to retrieve
* files. It is not robust at all, probably buggy, and definitely poorly
* designed. It's just meant to show that it can be done.
*
* Basically, you compile this code, and run it:
* ./physfshttpd archive1.zip archive2.zip /path/to/a/real/dir etc...
*
* The files are appended in order to the PhysicsFS search path, and when
* a client request comes it, it looks for the file in said search path.
*
* My goal was to make this work in less than 300 lines of C, so again, it's
* not to be used for any serious purpose. Patches to make this application
* suck less will be readily and gratefully accepted.
*
* Command line I used to build this on Linux:
* gcc -Wall -Werror -g -o bin/physfshttpd extras/physfshttpd.c -lphysfs
*
* License: this code is public domain. I make no warranty that it is useful,
* correct, harmless, or environmentally safe.
*
* This particular file may be used however you like, including copying it
* verbatim into a closed-source project, exploiting it commercially, and
* removing any trace of my name from the source (although I hope you won't
* do that). I welcome enhancements and corrections to this file, but I do
* not require you to send me patches if you make changes.
*
* Unless otherwise stated, the rest of PhysicsFS falls under the GNU Lesser
* General Public License: http://www.gnu.org/licenses/lgpl.txt
*
* This file was written by Ryan C. Gordon. (address@hidden).
