# This target builds all "normal" Linux installers.
#
# The bot setup is to build stable, unstable, and beta packages for the current
# build. Then a later step picks up the package corresponding to what the
# current build is supposed to be. This is wasteful since one build will only
# be one of these.
#
# TODO it would be much nicer to have a build variable so the bot can tell us
# what the current build should be, so we only have to make one .deb/.rpm pair.
#
#
# TO BUILD LINUX INSTALLER PACKAGES
#
# The packages list the exact versions of each library used. The versions used
# on the bots are likely different than those on your workstation, so you'll
# get a stream of errors like:
#   < libasound2 (>= 1.0.23)
#   ---
#   > libasound2 (>= 1.0.16)
#
# To avoid these warnings for testing purposes, do:
#
#   export IGNORE_DEPS_CHANGES=1
#
# before you build.
