Examples
Installing a tool using the DNF Cake Module is as simple as:
#tool dnf:?package=glx-utils
If the tool in question comes from a different source, you can change that as follows:
#tool dnf:http://fedora.uberglobalmirror.com/fedora/linux/updates/25/x86_64/?package=glx-utils
To install a specific version of a package:
#tool dnf:?package=glx-utils&version=8.3.0
or to tell DNF to use the "best" available version:
#tool dnf:?package=glx-utils&best
Full parameter information is covered in the parameters documentation.
