tests

Hi,

I have added/commited a lot of files in order to have an easy way to test.
The test script is test.sh.
The tested manuals are: 
* test cases
GermanNodeTest/nodetest.texi, sectionning

* "real" manuals
texinfo, cvs, xemacs, viper, viper monolithic, texi2html

The resulting/reference files are, for each $manual in $manual_res. I have 
commited the resulting files for GermanNodeTest, xemacs and texi2html because 
they seem right to me.

The cvs manual seems right too, but I am not certain.

viper and sectionning manuals have issues with unnumbered sections.

the texinfo manual has issues with unnumbered sections, @includecopying,
@verb and @verbatim are not handled correctly.

I still think that it should be nice to have a test case with some TeX in it.

Could you please have a look at the resulting manuals and check that the
result is indeed the right one ?

Pat
