* guix/import/cran.scm (download): Handle the case where URL is a list. (fetch-description-from-tarball): New procedure. (fetch-description): Add #:version parameter. Honor it when REPOSITORY is 'cran. Use 'fetch-description-from-tarball' when REPOSITORY is 'bioconductor. (description->package): SOURCE-URL may now be a list. (cran->guix-package): Pass VERSION to 'fetch-description'. (cran-recursive-import): Add #:version parameter. * guix/scripts/import/cran.scm (guix-import-cran): Expect a spec rather than a mere package name. * doc/guix.texi (Invoking guix import): Document it.
