/*
 * "untar" is an extremely simple tar extractor:
 *  * A single C source file, so it should be easy to compile
 *    and run on any system with a C compiler.
 *  * Extremely portable standard C.  The only non-ANSI function
 *    used is mkdir().
 *  * Reads basic ustar tar archives.
 *  * Does not require libarchive or any other special library.
 *
 * To compile: cc -o untar untar.c
