This patch adds --evr, --nevr, --name and --url commands extracting useful information from a spec file.
-r, --evr display the package version -a, --nevr display the package name-version -N, --name display the package name -u, --url, --URL display the package home page URL
Add --evr, --nevr, --name and --url commands to spectool spectool-evr.patch
I'd rather not add them, because all that information is already available with e.g. {{{rpm -q --qf="%{URL}\n" --specfile foo.spec}}} etc and the functionality seems out of spectool's scope.
