Drawing sequence diagrams with dia

["Per Olesen" <polesen nordija com>]

Hi,

Can I draw sequence diagrams with dia?

I looked through the various shapes and could only find "lifeline" in the
UML bunch of shapes, which looks like something I should use in a sequence
diagram. But I am having trouble using it.

I searched the archives and googled for an answer, but either dia cannot
be used for it, or it is so simple that I am missing how, and everyone
else knows how :-)

?
