dput-ng is a from-scratch refresh of the old dput(1)
command. This tool is
used (at some point) to aid with the act of uploading a package to an archive.
dput-ng aims to be compatible with the old dput(1)
config files, while
adding additional features for better sanity checking, and designed in an
extensible way.
