* gnu/packages.scm (find-newest-available-packages): New exported procedure. * guix-build.in (newest-available-packages, find-best-packages-by-name): New procedures. (find-package): Use find-best-packages-by-name, to guarantee that if a version number is not specified, only the newest versions will be considered. * guix-package.in (%options): Add --upgrade/-u option. (newest-available-packages, find-best-packages-by-name, upgradeable?): New procedures. (find-package): Use find-best-packages-by-name, to guarantee that if a version number is not specified, only the newest versions will be considered. (process-actions): Implement upgrade option. * doc/guix.texi (Invoking guix-package): In the description of --install, mention that if no version number is specified, the newest available version will be selected.
