[wprc/doc] Moved documentation from Texinfo to Latex (work in progress)

this was done with the help of
- https://github.com/sarabander/sicp-pdf/blob/master/src/texi-to-latex.pl
- http://savannah.nongnu.org/projects/texi2latex

The following steps
1. wrpc.in was converted to tex using texi-to-latex.pl
2. wrpc.in was converted to ltx using texi2latex
3. the output of texi-to-latex.pl was taken as the basis
4. one concept from the output of texi2latex was taken to replace @sc{}
5. document was fixed by hand by:
   - replacing, e.g.
     @uref         => \url
     @table @code  => \begin{itemize}
     @end table    => \end{itemize}
     @sc{          => \codeHook{
     @example      => \begin{lstlisting}
     etc
   - fixing tables
   - fixing annexes

this version:
- fails to fully compile but entire document is genreated
- still needs quite some work, especially with links to sections
