debian2dsc - generate a dsc file from a debian directory
Usage: dht debian2dsc [-o output/] [dir ...]
Expects directories containing the contents of the debian/ directory of a
Debian source package (i.e. control, changelog, watch, ...). Uses the watch
file to retrieve the upstream tarball (unless it already exists in the local
directory), creates a debian.tar.xz tarball from the given directory (ignoring
the ususal suspects like _darcs and *~) and creates a corresponding .dsc file;
all without unpacking the upstream tarball.
__END__

Usage: dht debian2dsc [-o output/] [dir ...]
Expects directories containing the contents of the `debian/` directory of a
Debian source package (i.e. `control`, `changelog`, `watch`, ...). Uses the watch
file to retrieve the upstream tarball (unless it already exists in the local
directory), creates a `debian.tar.xz` tarball from the given directory (ignoring
the ususal suspects like `_darcs` and `*~`) and creates a corresponding `.dsc` file;
all without unpacking the upstream tarball.
