sdedit - Quick Sequence Diagram Editor

My coworker pointed me to this tool and I found it very useful.
Quick Sequence Diagram Editor is a tool for creating UML sequence diagrams from textual descriptions of objects and messages that follow a very easy syntax.


Below you may see a syntax example for Sequence Diagram shown in screenshot - it's very intuitive and easy to understand.

user:Actor
/order:Order
db:TicketDB
acc:Account

user:order.new()
order:return=db.reserve(date,count)
db:return=acc.debit(cost)
acc:return=db.bonus(date,count)
user:order.destroy

The tool supports actors, constructors, destructors, threads and on-diagram comments that can be used to represent conditions or loops.
Diagrams can be exported in PNG format.
