# This makefile builds "fastprep", a faster version of prep.py that can be used
# to build training data for Swivel.
#
# = Step 1. Install protobuf v3 =
#
#   Ubuntu 16.10+: sudo apt install libprotobuf-dev
#   Ubuntu 16.04: https://launchpad.net/~maarten-fonville/+archive/ubuntu/ppa + replace xenial with yakkety in /etc/apt/sources.list.d/maarten-fonville-ubuntu-ppa-xenial.list
#   macOS: brew install protobuf
#
# = Step 2. Build "fastprep". =
#
#   make -f fastprep.mk
#
# If all goes well, you should have a program that is "flag compatible" with
# "prep.py" and runs significantly faster.  Use it to generate the co-occurrence
# matrices and other files necessary to train a Swivel matrix.
