+% @macro.
+% The basic scheme is as follows:
+% We read the first line and split it up into macro name and parameter
+% list.  We then walk the parameter list defining control sequences
+% named \MAC@<macro name><parameter name>.  Each expands to another
+% control sequence named \MAC@<macro name>.<parameter number>.  Those
+% control sequences will be defined at macro runtime to be the
+% parameter expansion text.
+%
+% The body is then read in as a single argument in a context where \
+% is an active character, and the cs \MACb.<macro name> is defined as
+% the macro body.  The active character \ takes one argument delimited
+% by another \, and uses it to index the table of macro arguments
+% described above.
+%
+% Finally, we define a control sequence \<macro name> which calls one
+% of the six (!) macro execution commands.  These six commands
+% correspond to recursive and nonrecursive macros with no, one, and
+% many arguments.  They all take one argument, <macro name>, set up
+% the environment appropriately, and call the real macro.
+%
+% \macsave@<macro name> holds the old definition of \<macro name>.
