-# See: https://github.com/jeking3/boost-ci/

-# Instructions for customizing this script for your library:
-#
-# 1. Customize the compilers and language levels you want.
-# 2. If you have move than include/, src/, test/, example/, examples/,
-#    benchmark/ or tools/ directories, set the environment variable DEPINST.
-#    For example if your build uses code in "bench/" and "fog/" directories:
-#      - DEPINST: --include bench --include fog
