To compile our feature processing binaries:
./init-script/build.sh
This will also install/compile all the external dependencies such as Indri and
WANDbl. Programs and header files will be installed at external/local/bin.
To install python dependencies:
pip install -r python/requirements.txt
Other bash scripts and Makefiles under experiments should work out of the box.
