# Installs folly's dependencies to /usr/local on a clean Ubuntu 12.04 x64
# system.  Primarily intended for Travis CI, since most engineers don't run
# distributions this stale.

# WARNING: Uses 'sudo' to upgrade your system with impunity:
#  - Adds several PPAs for missing/outdated dependencies
#  - Installs several from-source dependencies in /usr/local
#
# Library sources & build files end up in folly/folly/deps/
