+%% TeX hints:
+%% - @ is considered a normal letter in packages and classes
+%% - There are 256 32Bit \count<num> registers (i.e. \count0=42),
+%% can be expanded with \the<register> (i.e. \the\count0)
+%% - \relax ends scanning for tokens
+%% (i.e. \count0=\macro 42 <> \count0=\macro\relax 42)
+%% - A macro defined with can has a maximum of 9 arguments
+%% - \gdef is shortcut for \global\def
+%% \xdef is shortcut for \global\edef
+%% - \string<\macro> returns the "macro" (the name of a macro)
+%% Doc hints:
+%% - There must be _exactly_ four spaces between the "%" and the
+%% "\begin{macrocode}" or "\end{macrocode}. Otherwise, Doc
+%% won't detect the end of the code fragment.
+%% - The lines of code withen \begin{macrocode}...\end{macrocode}
+%% get written exactly as is to the .ins file, with no %-stripping.
