	Ok, Charilaos

dumping precompiled tex is a very old and useful technique you should  
try.  You only need to bundle all the styles and headers you used to  
use for making some kind of LaTeX document and after that  
usepackages.. put

\dump


then you will be asked for the name of the format.fmt file.  Put that  
file in the usual tex searched paths and vuala!  you can use it in

	pdflatex -f format.fmt source.tex

saving you not only many processor cycles but making your every day  
documents shorter and cleaner

	%&format
	% Author: me
	%...

	\begin{document}

	\end{document}

this came from the very first times of tex and is of course used by  
TeXShop, OzTex, and my terminal Tcl scripts ;)

	You are wright, not every latex doc need to produce .toc files and  
then it is more difficult to discover that.  You need to make a first  
typesetting, if no previous .aux and now is there one a second one  
will be necessary, and if no previous .toc file and one now appears,  
a third one will be necessary.  In the meanwhile, you also will need  
to watch .bbl files from bibtex that should be run if some .bbl  
appears, etc.
