-lrzip (Long Range ZIP or Lzma RZIP) is a file compression program designed
-to do particularly well on very large files containing long distance redundancy.
+Long Range ZIP or Lzma RZIP
 
-lrztar is a wrapper for lrzip to simplify compression and decompression
-of directories. lrzip uses an extended version of rzip which does a first pass
-long distance redundancy reduction. The lrzip modifications make it scale
-according to memory size. The data is then either:
-1. Compressed by lzma (default), zpaq, lzo, gzip or bzip2.
-2. Left uncompressed and rzip prepared.
+This is a compression program optimised for large files. The larger the file
+and the more memory you have, the better the compression advantage this will
+provide, especially once the files are larger than 100MB. The advantage can
+be chosen to be either size (much smaller than bzip2) or speed (much faster
+than bzip2).

+3. Only stdin in compression works well. The other combinations of
+   stdin/stdout work but in a very inefficient manner generating temporary
    files on disk so this method of using lrzip is not recommended.
 4. Files compressed on a 64 bit OS with a compression window greater than 20
    (2 GB) may not decompress on a 32 bit OS.
 
 See the file README.benchmarks for performance examples and what kind of data
 lrzip is very good with.

+NOT BACKWARD COMPATIBLE WARNING
+All files created with lrzip 0.50+ are not backward compatible with versions
+prior to 0.50. v0.50 can read earlier generated files.
