# NOTE: `cabal test` will take care to build the local `alex`
# executable and place it into $PATH for us to pick up.
#
# If it doesn't look like the alex binary in $PATH comes from the
# build tree, then we'll fall back to pointing to
# ../dist/build/alex/alex to support running tests via "runghc
# Setup.hs test".
#
# If ALEX has been set outside, e.g. in the environment, we trust this setting.
# This way, we can pass in the correct Alex executable from a CI environment
# without danger of it being "fixed" by the logic below.
