### Usage:
### build-proot.sh [-h] -a i386|amd64 [-b build-options] [-S] [-R] [-V middle-part] -o focal|jammy|noble [-s focal|jammy|noble] package...
###
### Options:
### -a architecture ... i386 or amd64
### -o os ............. target: focal (20.04) or jammy (22.04) or noble (24.04)
### -s os ............. source: focal (20.04) or jammy (22.04) or noble (24.04)
### -S ................ create source package, too
### -V middle-part .... middle part of version number, i.e. 2.4-0~uh~focal1
### -i image.tar.xz ... lxc image file
### -R ................ use "root" for build (required by GOCRYPTFS for example)
### -b build-options .. prepend 'dpkg-buildpackage' with build-options
### -k ................ keep sources even on failures
### package ........... package to build
