## This is used to package .deb packages and upload them to the launchpad
## ppa servers for building.
##
## If no argument is given, creates a package for the develop branch
## and uploads it to the ethereum/ethereum-dev ppa.
##
## If an argument is given, it is used as a tag and the resulting package
## is uploaded to the ethereum/ethereum ppa.
##
## The gnupg key for "builds@ethereum.org" has to be present in order to sign
## the package.
##
## It will clone the Solidity git from github, determine the version,
## create a source archive and push it to the ubuntu ppa servers.
##
## This requires the following entries in /etc/dput.cf:
##
##  [ethereum-dev]
##  fqdn			= ppa.launchpad.net
##  method			= ftp
##  incoming		= ~ethereum/ethereum-dev
##  login			= anonymous
## 
##  [ethereum]
##  fqdn			= ppa.launchpad.net
##  method			= ftp
##  incoming		= ~ethereum/ethereum
##  login			= anonymous
