+% The declaration takes 3 mandatory arguments: an \emph{encoding}
+% for which a subsetting is wanted (currently always \texttt{TS1},
+% and most likely forever), the \emph{font family} for which we
+% declare the subset and finally the \emph{subset} number, with a value between
+% \texttt{0} (all of the encoding is supported) and \texttt{9} (many
+% glyphs are missing).
+%
+% For \texttt{TS1} the numbers have been chosen in a way that most
+% fonts can be fairly correctly categorized, but the default
+% settings are always conservative, that is they may claim that
+% fewer glyphs are supported than there actually are.
+%
+% As these days many font families are set up to end in \texttt{-LF}
+% (lining figures), \texttt{-OsF} (oldstyle figures), etc.\ the
+% declaration supports a shortcut: if the \emph{font family} name
+% ends in \texttt{-*} then the star gets replaced by these common
+% ending, e.g.,

+% message. the code in that argument (if ever executed) receives
+% two arguments: |#2| and |#5| of |\CheckEncodingSubset|.
+%
+% Argument four is the subset encoding id to test against: if this
+% value is higher than the subset id of the current font family
+% then we typeset the symbol, i.e., execute |#1{#2}#5| otherwise
+% it runs |#3#5|, e.g., to produce an error message or fake the
+% glyph somehow.
