+python3-lz4: provides python bindings for the LZ4 compression library.
+
+The python3 bindings provided in this package cover the frame format
+and the block format specifications. The frame format bindings are the
+recommended ones to use, as this guarantees interoperability with other
+implementations and language bindings.
+
+The API provided by the frame format bindings follows that of the LZMA,
+zlib, gzip and bzip2 compression libraries which are provided with the
+Python standard library. As such, these LZ4 bindings should provide a
+drop-in alternative to the compression libraries shipped with Python.
+The package provides context managers and file handler support.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
