    Provide support for authors that want to distribute packages, by
    expanding occurrences of "${foo}" in an input package spec with
    the value of the 'foo' environment variable. This permits easy
    configuration at install-time, e.g.,
      $ libdir=/opt/haskell/packages/lib ghc-pkg -a < NewPackage.pkg
    [Clearly, a separate preprocessing pass using some other tool could
     provide identical functionality. However, the benefits to the
     package author of not having to depend on such a tool being present
     on a user's box was considered more important.
