Drawing Sequence Diagrams

Question

I'm looking for an easy language/command line utility to draw sequence and timing diagrams (could be 2 different tools). I've already found Mscgen for sequence diagram drawing and looks pretty good, but I'm studying other possibilities.

Thanks

The best software I've found and I usually use to make sequence diagrams from plain text is SDEdit. It's a Java tool, so you can use it in any operating system. And it's free software!

#![SD ticket order]
ext:External[pe]
user:Actor
/order:Order[x]
db:TicketDB
acc:Account

ext:user.order a ticket!
user:order.new()
order:return=db.reserve(date,count)
db:return=acc.debit(cost)
acc:return=db.bonus(date,count)

to obtain this:
