Install missing LaTeX styles and definitions

When I was compiling my report, some files are missing:

! Package fontenc Error: Encoding file `eu1enc.def' not found.

An interesting installation of relatex packages is, you can install the missing files by providing this command:

dnf install 'tex(eulenc.def)'

It is benefited from RPM’s provides tag, documented here.
