Beams across bars across systems

[Bart Diels]

L.S.,

As a Lilypond newbie I encounter problems with the following.

In a certain part of my piece the melody line typically exists of an
alternation of quaver rests and quavers. All quavers that belong to one
phrase are linked by beams. Those beams usually go across bar lines. As many
phrases do not begin on the first quaver of a measure (and therefore do not
end on the last quaver of a measure), almost every bar line is crossed by a
beam. But, as page width is not infinite, beams do not only cross bar lines,
but systems as well.

What I would like to obtain, are systems in which the last bar ends with a
beam sticking out, followed by a system in which the first bar begins with a
beam leading to the first quaver.

I can't get that right: I end up with a score in which the last system just
runs off the page, with may bars disappearing into nothingness.

This is what the compiler says:
