-/*
- * qt-faststart.c, v0.1
- * by Mike Melanson (melanson@pcisys.net)
- * This file is placed in the public domain. Use the program however you
- * see fit.
- *
- * This utility rearranges a Quicktime file such that the moov atom
- * is in front of the data, thus facilitating network streaming.
- *
- * To compile this program, start from the base directory from which you
- * are building FFmpeg and type:
- *  make tools/qt-faststart
- * The qt-faststart program will be built in the tools/ directory. If you
- * do not build the program in this manner, correct results are not
- * guaranteed, particularly on 64-bit platforms.
- * Invoke the program with:
- *  qt-faststart <infile.mov> <outfile.mov>
- *
- * Notes: Quicktime files can come in many configurations of top-level
- * atoms. This utility stipulates that the very last atom in the file needs
- * to be a moov atom. When given such a file, this utility will rearrange
- * the top-level atoms by shifting the moov atom from the back of the file
- * to the front, and patch the chunk offsets along the way. This utility
- * presently only operates on uncompressed moov atoms.
