# Each item under 'env' is a separate Travis job to execute.
# They run in separate environments, so each one must take the time
# to clone the repository and submodules; to download and install SDKs,
# pip packages, and so forth.  By gathering activities together in optimal
# ways, the "run time" and "total time" of the travis jobs can be minimized.
#
# Since at the time of writing Travis generally starts 5 or 6 jobs, the
# builds have been organized into 5 groups of *approximately* equal durations.
# Additionally, the jobs that need extra SDKs are also organized together.
#
# When adding new boards, take a look on the travis CI page
# https://travis-ci.org/adafruit/circuitpython to which build that installs
# that SDK is shortest and add it there.  In the case of major re-organizations,
# just try to make the builds "about equal in run time"
