Create template for approximating the resulting package

[pvalena]

Like an "update" template.

Good for comparison with an existing .spec file. This template would not have any "begginers" / "helper" entries with (unnecessary) comments, and also no disabled BuildRequires, and rspec spec in %check (it would be all uncommented instead). The goal would be to approximate as closely as possible the actual working specfile.

Significant amount of logic could be added as well (like "no coverage" tools in BuildRequires, and packaging upstream test suite f.e.).

WDYT?
