-# Command-line tool to decompress mozLz4 files used for example by Firefox to store various kinds of session backup information.
-# Works in both Python 2.7.15 and 3.6.7, as of version 2.1.6 of the LZ4 Python bindings at pypi.org/project/lz4.
-# To use in another script, simply cut and paste the import statement and the mozlz4_to_text() function (lines 8 to 17).
