# DESCRIPTION:
# ============
# Vagrant for running libevent tests with:
# - timeout 30min, to avoid hungs
# - run tests in parallel under ctest (10 concurency)
# - if you have uncommited changes, you should commit them first to check
# - unix only, because of some tar'ing to avoid one vm affect another
#
# ENVIRONMENT:
# ============
# - NO_PKG        -- do not install packages
# - NO_CMAKE      -- do not run with cmake
# - NO_AUTOTOOLS  -- do not run with autoconf/automake

Vagrant.configure("2") do |config|
  # to allow running boxes provisions in parallel, we can't share the same dirs
  # via virtualbox, however sometimes it is the only way, so instead let's
  # create an archive of HEAD (this way we will not have any trash there) and
  # extract it for every box to the separate folder.
  #
  # P.S. we will change this --prefix with tar(1) --trasnform
