+# Generic Travis CI build script for boostorg repositories
+# See: https://github.com/jeking3/boost-ci
+#
+# 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.
