-# Purpose:
-# - To test and prove that a new commit in  the mbed TLS repository builds
-# and integrates with mbed-os properly.
-#           AND
-# - To test and prove that the current development head of mbed TLS builds
-# and integrates with the current mbed-os master branch.
-#
-# The script fetches all the prerequisites and builds the mbed TLS 'tls-client'
-# example. This script is triggered by every commit and once each night and the
-# exact behaviour depends on how it was triggered:
-# - If it is a nightly build then it builds the mbed TLS development head with
-#   mbed-os master.
-# - If it was triggered by the commit, then it builds the example with mbed TLS
-#   at that commit and mbed-os at the commit pointed by mbed-os.lib in the
-#   example repository.
