+> packages ([reverse-argparse][reverse-argparse],
+> [staged-script][staged-script]), and we hope to do the same with more
+> functionality in the future.  For the time being, though, don't expect much
+> development and maintenance here.  That said, if you use `shell-logger` and
+> are eager to contribute to its longevity, let us know.
