# A script to bootstrap dokku.
# It expects to be run on Ubuntu 14.04 via 'sudo'
# If installing a tag higher than 0.3.13, it may install dokku via a package (so long as the package is higher than 0.3.13)
# It checks out the dokku source code from Github into ~/dokku and then runs 'make install' from dokku source.

# We wrap this whole script in a function, so that we won't execute
# We wrap this whole script in functions, so that we won't execute
# until the entire script is downloaded.
# That's good because it prevents our output overlapping with wget's.
# It also means that we can't run a partially downloaded script.
