Add a declarative packaging layer.
Add a declarative packaging layer.
* Makefile.am (MODULES): Add `guix/packages.scm' and `distro/base.scm'. (TESTS): Add `tests/packages.scm'. (EXTRA_DIST): New variable. * guix/packages.scm, distro/base.scm, tests/packages.scm: New files. * guix/http.scm (http-fetch): Make `name' an optional argument, to match the expectations of `package-source-derivation'.version-0.8.3
