+% \@startsection 
+% {NAME}{LEVEL}{INDENT}{BEFORESKIP}{AFTERSKIP}{STYLE} 
+%         optional * [ALTHEADING]{HEADING}
+%    Generic command to start a section. 
+%    NAME       : e.g., `subsection'
+%    LEVEL      : a number, denoting depth of 
+%                 section -- e.g., chapter=1, 
+%                 section = 2, etc.
+%    INDENT     : Indentation of heading from left 
+%                 margin
+%    BEFORESKIP : Absolute value = skip to leave 
+%                 above the heading. If negative, 
+%                 then paragraph indent of text 
+%                 following heading is suppressed.
+%    AFTERSKIP  : if positive, then skip to leave 
+%                 below heading, else negative of 
+%                 skip to leave to right of run-in 
+%                 heading.
+%    STYLE      : commands to set style
+%  If `*' missing, then increments the counter.  
+%  If it is present, then there should be no 
+%  [ALTHEADING] argument.  Uses the counter 
+%  `secnumdepth' whose value is the highest section 
+%  level that is to be numbered.
