64 % \section{Introduction}
65 %
66 % This file defines the package |latexsym| which makes the few
67 % additional characters available that come from the |lasy| fonts
68 % (\LaTeX's symbol fonts). These fonts are not automatically
69 % included in the NFSS2/\LaTeXe{} since they take up important
70 % space and aren't necessary if one makes use of the packages
71 % \texttt{amsfonts} or \texttt{amssymb}.
72 %
73 % The commands defined by the \texttt{latexsym} package are:
74 % \begin{quote}\raggedright
75 % |\mho|~$\mho$ \quad
76 % |\Join|~$\Join$ \quad
77 % |\Box|~$\Box$ \quad
78 % |\Diamond|~$\Diamond$ \quad
79 % |\leadsto|~$\leadsto$ \quad
80 % |\sqsubset|~$\sqsubset$ \quad
81 % |\sqsupset|~$\sqsupset$ \quad
82 % |\lhd|~$\lhd$ \quad

90 % \section{The \dst{} modules}
91 %
92 % The following modules are used in the implementation to direct
93 % \dst{} in generating the external files:
94 % \begin{center}
95 % \begin{tabular}{ll}
96 % driver & produce a documentation driver file \\
97 % package & produce a package file \\
98 % fd & produce a font definition file
99 % \end{tabular}
100 % \end{center}

103 % \section{The Implementation}
104 %
105 % The individual files generated from this code are identified at the
106 % very top of this file by a couple of lines looking like this:

118 % \begin{macro}{\symlasy}
119 %
120 % It is possible to detect whether or not the \LaTeX{} symbols are
121 % already defined by checking for the math group number with the
122 % name |\symlasy|.
123 %
124 % In that case we exit but write a message to the transcript file.
125 % \begin{macrocode}
126 \ifx\symlasy\undefined \else

130 % Otherwise we define the new symbol font.

133 \SetSymbolFont{lasy}{bold}{U}{lasy}{b}{n}
134 % \end{macrocode}
135 % \end{macro}
136 %
137 %
138 % Because the lasy symbols are made an error in the format we have
139 % to undefine them before we can set them anew with
140 % |\DeclareMathSymbol|.

163 % To save some space we can remove the definition of |\not@base|
164 % since it isn't any longer needed. (We use |\@undefined| so that
165 % gives an error and not a recursive definition

185 % Since there are no bold lasy symbols below 10pt we silently
