version: ~> 1.0

# If the language is set to C or C++, Travis defines and exports CC
# and CXX *after* we have defined our environment variables via 'env'.
language: minimal

# Run in two steps:
# 1. Build the tarball
#    On a modern distro, with all the needed dependencies, including the whole git history.
# 2. Check it on various environments.
#    Less dependencies, and little git content (we would like to have none, but it's not
#    an option on Travis).
stages:
  - dist
  - check

# The 'check' jobs do not need the repo at all, only the 'dist'
# does.  Let's save time, bandwith, energy, and polar bears.

  clone: false

# matrix.include and jobs.include are aliases
