typo (commit because I need a clean working tree)
Add comment on character encoding
uncomment ulCFPstyles
review up to section 4 (how does it work)

mainly slight rewordings
Slight restructuring of sect 4-5-6

section 5 (Project structure) is _not_ "a rather personal report of our
experiences"...

First I thought it should be yet another subsection below 3, but I think
it should simply be another section between 4 and 6.

Maybe it will require a new intro to 6.
Review "Project structure"
Review sections 6 and 7
Review end of paper
