+  \noindent Adding \texttt{-embed-std14 <directory>}, given a directory holding the GhostScript/URW free fonts, will embed subsetted font files in the PDF for any of the Standard fonts used. These free fonts can be downloaded from \url{https://github.com/ArtifexSoftware/urw-base35-fonts}. This is important, for example, for PDF/A documents, which must have their fonts embedded.
+
+The standard fonts cover only the Latin characters, and are limiting. Other TrueType fonts may be introduced with the \texttt{-load-ttf} option, giving a name for, and the file name of the font. For example:

   \subsection{Colors}

   The \texttt{-color} option takes an RGB (3 values), CYMK (4 values), or Grey (1 value) color. Components range between 0 and 1. All the standard web colours \url{https://www.w3.org/wiki/CSS/Properties/color/keywords} are provided as RGB components, and may be selected by name.
