ifetex – Provides \ifetex switch
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 \ε-TeXversion is defined as
a primitive; if it is, the package assumes e-TeX features are
available.
