+ * This utility rearranges a Quicktime file such that the moov atom
+ * is in front of the data, thus facilitating network streaming.
+ *
+ * Compile this program using:
+ *  make qt-faststart
+ * 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.
