157 is included. The LZ4 algorithm can run in-place as long as the
158 compressed image is loaded to the end of the output buffer, and
159 trades lower compression ratios for much faster decompression.

161 NOTE: This implements the release version of the LZ4 frame
162 format as generated by default by the 'lz4' command line tool.
163 This is not the same as the outdated, less efficient legacy
164 frame format currently (2015) implemented in the Linux kernel
165 (generated by 'lz4 -l'). The two formats are incompatible.
