find-regressions.sh

#!/bin/bash

# # Instructions
#
# Run the script like (from the root folder) :
#
#     ./find-regressions.sh some-folder/
#
# To run it on all Elm packages in your ELM_HOME, run:
#
#     ./find-regressions.sh ~/.elm/0.19.1/
#
# The version it will compare to is the one in `find-regressions/published/elm.json`
# under the `dependencies.direct.['stil4m/elm-syntax']` field.
#
# The script will also give performance metrics.
# If you only want to get that (and don't care about the regression check), run:
#
#     ./find-regressions.sh --no-check some-folder/
#
