[texhax] modifying \@startsection

[Michael Barr]

I will tell you my secret for modifying section starts and similar things.  
I have made a number of such modifications, but I would not have been able 
had I had only LaTeX2e available.  The best such documentation for LaTeX 
is found in latex.tex, the source for the old original LaTeX.  The section 
macros have been copied verbatim, I believe, into LaTeX2e, but without the 
original comments that make it relatively easy to modify.  

It is still available from CTAN in a directory called something like 
obsolete.  As source code, much of it is obsolete, but for documentation, 
it is gold.
