# Stages are useful only to enforce some ordering of the jobs. Every job is run

# in its own directory and only very few data can be shared between the jobs in

# different stages. It has to be zipped and uploaded to the server, so we can't

# do it with the build directory. Hence, we must build, test and install in the

# same job.
