- * Changelog:
- * 2005-04-26 - Define the header as a C structure, add a CRC32 checksum to
- *              the header, and make all the types 32-bit.
- *                --Benjamin Smedberg <benjamin@smedbergs.us>
- * 2009-03-31 - Change to use Streams.  Move CRC code to crc.{h,cc}
- *              Changed status to an enum, removed unused status codes.
- *                --Stephen Adams <sra@chromium.org>
- * 2013-04-10 - Added wrapper to apply a patch directly to files.
- *                --Joshua Pawlicki <waffles@chromium.org>
