# This script sets up Travis CI with the following matrix:
#
# linux: gcc  , make check, qucs-test, gcov, coveralls integration
# linux: clang, make check, qucs-test, doxygen deploy
# osx:   clang, make check, qucs-test
#
# The matrix tries to balance the run time of the instances instead of
# creating new instances for shorter jobs.
#
# Most time consuming tasks:
# - setup of gcc
# - gcov data collection
# - install Qt on OSX
# - doxygen build (master only)
