\section{Description}
    The `zd' fonts by Constantin Kahn (\verb<kahn@math.uni-hannover.de<)
    are virtual T1 encoded Computer Modern fonts based on (OT1) Computer Modern,
    Times, and Helvetica fonts, intended for simulate `dc'
    fonts.\footnote{Waine Sullivan's `dm' fonts are another approach to
    the substitution of `dc' fonts by virtual ones.}

    Because `dc' fonts are now obsolete, I've adapted the Kahn's package to
    `ec' fonts. The resulting virtual fonts are named according to the ec
    fonts names, changing `ec' by `ze' (\verb+zerm1000.vf+
    simulates \verb+ecrm1000+, and so on).
\section{Installation}
    The installation is very easy: you only need to put every file in its
    correct directory.
    \begin{itemize}
        \item Copy all the files from the \verb+vf+ directory where your
        dvi driver can find virtual files.\footnote{Your dvi driver must
        support virtual fonts, of course.}
        \item Copy all the files from the \verb+tfm+ directory where \TeX{}
        look for font metrics.
        \item Copy all the files from the \verb+texinput+ directory
        where \LaTeX{} look for input files.
        \item If you have the \verb+dvips+ driver, copy the files from the
        \verb+dvips+ directory where \verb+dvips+ looks for font mapping.
    \end{itemize}
\section{Warnings}
\begin{itemize}
\item
This is an unsupported software, and it comes without any kind of warranty.
\item
You can distribute it freely.
\item
My work for construct the `ze' fonts was a simple adaptation from the
`zd' fonts by C. Khan.
