\item[Package name:] {\tt newtxtt} (Typewriter fonts from {\tt txfonts})
\item[Derived from:] Original design to match width of {\tt cmtt}, but weight and height of Times. 
\item[Weights and shapes:]  \{m, b\}, \{n, sl\}. 
\item[Features:]{\color{white}x}\\[-15pt]  
\begin{itemize}
\item few encodings available: T1, TS1;
\item four forms of `zero' to choose from with option {\tt zerostyle} one of {\tt a, b, c, d}---the default is {\tt a}, an unslashed {\tt 0}, narrower than the capital letter {\tt O}; 
\item \texttt{\textsc{Small Caps}} variant in upright shapes only;
\item variants are available (option {\tt space}) which provide a limited form of text font, having the same monospaced glyphs, but permitting hyphenation and smaller (and variable) interword spacing---the macros \verb|\ttzdefault|, \verb|\ttzfamily|, \verb|\ttz| behave like their monospace cousins, while \verb|\nomono| changes the meanings of the \verb|\tt| macros to their \verb|\ttz| forms;
\end{itemize}
\item[Typical invocation:]{\color{white}x}
\begin{verbatim}
