-# Generic Travis CI build script for boostorg repositories
-#
-# Instructions for customizing this script for your library:
-# 
-# 1. Customize the compilers and language levels you want in the 'jobs'.
-# 2. If you have more than include/, src/, test/, example/, examples/, or
-#    tools/ directories, modify your Travis CI project and add the environment
-#    variable DEPINST.  For example if your build uses code in "bench/" and
-#    "fog/" directories, then set DEPINST to the following:
-#        --include bench --include fog
-# 3. 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.
-# 4. Enable pull request builds in your boostorg/<library> account.
-#
-# That's it - the scripts will do everything else for you.
