-- This handles the @sdist@ command. The module exports an 'sdist' action but
-- also some of the phases that make it up so that other tools can use just the
-- bits they need. In particular the preparation of the tree of files to go
-- into the source tarball is separated from actually building the source
-- tarball.
--
-- The 'createArchive' action uses the external @tar@ program and assumes that
-- it accepts the @-z@ flag. Neither of these assumptions are valid on Windows.
-- The 'sdist' action now also does some distribution QA checks.
