+% This is the driver file for the St Mary's Road symbol font, named
+% after the palatial mansion (currently under investigation by the
+% Enviromental Health Officer) where we lived, and where many of the
+% symbols were designed and discussed over a bottle of wine and some
+% halva.
+%
+% Many of the symbols are derived (or `stolen', to use the technical
+% phrase from Knuth's Computer Modern fonts, and the American
+% Mathematical Society's msam and msbm fonts. Please don't sue.
+
+% We assume the parameters have been set by whichever file called us
