-# Generic Azure Pipelines build script for boostorg repositories
-# See: https://github.com/boostorg/boost-ci/
-#
-# Instructions for customizing this script for your library:
-#
-# 1. Customize the compilers and language levels you want.
-# 2. If you have more 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
-# 3. Enable pull request builds in your boostorg/<library> account.
-#
-# That's it - the script will do everything else for you.
