Template Spec
-------------

Subcommands such as ``install`` and ``download`` accept one or more
*TEMPLATESPEC* strings. The format is, in essence, almost identical to
``<package-name-spec>`` described in the DNF documentation.

In short, the spec is matched against the following list of NEVRA forms, in
decreasing orders of priority:

* ``name-[epoch:]version-release``
* ``name``
* ``name-[epoch:]version``

Note that unlike DNF, ``arch`` is currently ignored as the template packages
should all be of ``noarch``.

One can also use globs in spec strings. See Section `Globs`_ for details.

Refer to Section *NEVRA Matching* in the DNF documentation for details.

Globs
-----

`Template Spec`_ strings, repo ids, and search patterns support glob pattern
matching. In particular, the following special characters can be used:

* ``*``: Matches any number of characters.
* ``?``: Matches exactly one character.
* ``[]``: Matches any enclosed character.
* ``[!]``: Matches any character except those enclosed.

In particular, note that ``{}``, while supported by DNF, is not supported by
`qvm-template`.
