ppabuild.sh

#!/bin/sh
##############################################################################
## This is used to package .deb packages and upload them to the launchpad
## ppa servers for building. It requires one argument (passed via env):
##
## ethbranch:   the branch to use for webthree-umbrella, either develop or
##              release
## debplatform: target ubuntu "release", i.e. trusty, vivid, wily or xenial
##              (we should switch to numbered releases at some point)
##
## The "debian" directories can be found in github.com/ethereum/ethereum-ppa
## The develop branch will be used for anything before wily, while wily and
## xenial have their own branches.
##
## The gnupg key for "build@ethdev.com" has to be present in order to sign
## the package.
##
## Caveats: A package with the same version number should not be uploaded
## multiple times to the build servers. This is not a big problem for the
## develop snapshots as the version will change with every commit, but
## for release packages, the version will be taken from the CMakeLists.txt
## file. This means that this script should only be run once for every
## release. If the source package was uploaded before, add '-sd' to the
## debuild command (see below).
