-# Generic Travis CI build script for boostorg repositories
-#
-# Instructions for customizing this script for your library:
-# 
-# 1. Copy the ci/ directory from the same source into your project:
-#    ci/build.sh runs the build
-#    ci/codecov.sh is used to run a profiling build and upload results to codecov.io
-#    ci/coverity.sh is used to run a coverity build and upload results coverity scan
-# 2. Customize the compilers and language levels you want.  Default is C++03.
-# 3. Update the global B2 environment settings to your liking.
-# 4. If you have more than include/, src/, and test/ directories then
-#    add them to the depinst.py line as "--include tools" for tools/ (you
-#    can put multiple --include on the command line).
-# 5. If you want to enable Coverity Scan, you need to provide the environment
-#    variables COVERITY_SCAN_TOKEN and COVERITY_SCAN_NOTIFICATION_EMAIL in
-#    your github settings.
-# 6. Enable pull request builds in your boostorg/<library> account.
-# 7. Change the default C++ version in ci/*.sh (search for CXXSTD)
-#
-# That's it - the scripts will do everything else for you.
