# Help Message
read -d '' usage <<- EOF
Usage: $scriptName [-c|u|v|b|s|B|o|h|j|m|] signer version

Run this script from the directory containing the dash, gitian-builder, gitian.sigs, and dash-detached-sigs.

Arguments:
signer          GPG signer to sign each build assert file
version		Version number, commit, or branch to build. If building a commit or branch, the -c option must be specified

Options:
-c|--commit	Indicate that the version argument is for a commit or branch
-u|--url	Specify the URL of the repository. Default is https://github.com/dashpay/dash
-v|--verify 	Verify the gitian build
-b|--build	Do a gitian build
-s|--sign	Make signed binaries for Windows and Mac OSX
-B|--buildsign	Build both signed and unsigned binaries
-o|--os		Specify which Operating Systems the build is for. Default is lwx. l for linux, w for windows, x for osx
-j		Number of processes to use. Default 2
-m		Memory to allocate in MiB. Default 2000
--kvm           Use KVM
--lxc           Use LXC
--docker        Use Docker
--setup         Setup the gitian building environment. Uses KVM. If you want to use lxc, use the --lxc option. If you want to use Docker, use --docker. Only works on Debian-based systems (Ubuntu, Debian)
--detach-sign   Create the assert file for detached signing. Will not commit anything.
--no-commit     Do not commit anything to git
-h|--help	Print this help message
