.travis.yml - bison - Git at Google

 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.
