# DESCRIPTION
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
# This script builds the project in a way that is convenient for developers.
# It passes the right flags into right places, builds the project with --fast,
# tidies up and highlights error messages in GHC output.

# USAGE
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#   ./b                 build whole project with all targets
#   ./b -c              do stack clean
#   ./b -t              build and run tests
#   ./b -b              build and run benchmarks
#   ./b --nix           use nix to build package
