Introduction
In this tutorial we learn how to install texlive-ifetex on CentOS 8.
What is texlive-ifetex
The package provides the switch \ifetex which indicates whether e-TeX is available or not. The package can be loaded as LaTeX package using \usepackage{ifetex} or in plain TeX using \input ifetex. In either case it aborts silently if the \ifetex macro is already defined. The package’s test is whether \eTeXversion is defined as a primitive; if it is, the package assumes e-TeX features are available.
