+lz4 (compression algorithm)
+
+LZ4 is lossless compression algorithm, providing compression speed at
+400 MB/s per core (0.16 Bytes/cycle). It also features an extremely fast
+decoder, with speed in multiple GB/s per core (0.71 Bytes/cycle). A high
+compression derivative, called LZ4_HC, is also provided. It trades CPU
+time for compression ratio.
+
+This build includes liblz4 and the command-line lz4 tools.

+# 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.
