Quickstart

# Clone the repo
git clone https://github.com/smarkets/erlbz2.git

# Fetch deps and build it
# *NOTE: proper may fail to build at first, so run make until it
# succeeds. I believe this is due to an oddity in rebar where
# warnings are treated as errors.
$ make

# Run tests to verify
$ make check

Compression

1> erlbz2:compress(<<"foo">>).

  1,0,160,0,33,0,130,44,93,201,...>>
