+trsym font
+
+author: Jan Holfert
+
+keywords: transformation, symbol, font, metafont
+     
+This font contains symbols used for transformations (e.g. Laplace
+transformation). There are horizontal and vertical symbols both for
+transformation and inverse transformation.
+To install the font it is only necessary to run the file trsym.ins through
+latex. The file trsym.dtx contains the style files and the documentation. To
+get the documentation run "latex trsym.dtx".

+% \section*{Installation}
+% If you see the symbols in section ``Usage'', the files are
+% already installed. There is no need to do the installation
+% again. Otherwise, do the following:
+% \begin{enumerate}
+% \item Create a subdirectory \textsf{trsym} in your local source path
+%   for \textsf{MetaFont} files. If you use the configuration file for
+%   the \textsf{docstrip} utility doing this is obligatory.
+% \item Run ``\textsf{latex trsym.ins}''. If you use \textsf{docstrips}'
+%   configuration file, everything is copied to its right
+%   place. Otherwise, copy \textsf{trsy.mf}, \textsf{trsy10.mf} and
+%   \textsf{trsy12.mf} into the subdirectory \textsf{trsym}
+%   (e.g. \bs\bs localtexmf\bs fonts\bs source\bs trsym). Copy
+%   \textsf{utrsy.fd} and \textsf{trsym.sty} into a subdirectory
+%   \textsf{trsym} in your local \LaTeX{} path (e.g. \bs\bs
+%   localtexmf\bs tex\bs latex\bs trsym)
+% \end{enumerate}
+% \section*{Usage}
+% Write \textsf{\bs usepackage\{trsym\}} into your \LaTeX{} file's preamble.
+% In \textsf{mathmode} use the following commands generating the
+% according symbol. The commands in parenthesis are short versions of
+% the commands as I used to declare in my documents.\\[1em]
+% \begin{displaymath}
+%   \begin{array}{lc}
+%       \mbox{command} & \mbox{symbol}\\
+%       \hline
+%       \mbox{\rule{0pt}{1.1em}\textsf{\bs TransformHoriz (\bs tfh)}} & \tfh\\
+%       \mbox{\textsf{\bs InversTransformHoriz (\bs itfh)}} & \itfh\\
+%       \mbox{\textsf{\bs TransformVert (\bs tfv)}} & \tfv\\
