Before opening the Tango manual with lyx, copy the layout files 
to the following directories in your home directory:

cp layouts/Tango_book.layout  ~/.lyx/layouts/Tango_book.layout
cp layouts/stdsections.inc  ~/.lyx/layouts/stdsections.inc
cp layouts/textclass.lst  ~/.lyx/textclass.lst
cp layouts/styFiles.lst  ~/.lyx/styFiles.lst

cp layouts/Tango_book.cls  ~/.TeX/Tango_book.cls


To create the html documentation use tango_latex2html to get
the correct splitting parameters and the correct line breaks.

In the case of an latex error as:
	missing tex class Tango_book
you might have to use the TEXINPUTS environment variable
to indicate where to find the Tango_book.cls file.
	export TEXINPUTS=$TEXINPUTS:~/.TeX
