I think this is a good example of "community problem solving" - solve it once, share, and it's solved for all of us!

One of the challenges in producing an Internet Draft is the creation of ASCII art call flow diagrams (aka sequence diagrams), such as those in http://www.ietf.org/rfc/rfc3665.txt. I tend to do a lot of these in the drafts I write.
To make the process easier, a colleague of mine, Dave Ladd, wrote a tool called callplot. Callplot takes a source file that describes the callflow, and then compiles it into an ASCII art version suitable for inclusion in Internet drafts. It does automatic message numbering, labeling, and so on. It can also spit out other formats that can be included in MS Office documents, for example.
To illustrate, running callplot on this input:
opt/columnPitch/15 guy/f/Fred guy/b/Barney f->b/Please note/b/Gives bowling ball b->f/Stuff b..f/RTP f->b/Thank You b->f/You're Welcome
produces this diagram:
Fred Barney | | | | | | |Please | |------------->| | | | | | |Gives bowling ball | | | | | | |Stuff | |<-------------| | | | | |RTP | |..............| | | | | |Thank You | |------------->| | | | | |You're Welcome| |<-------------| | | | | | | | |
I think this tool would be useful to the IETF community at large. As a result, we've decided to make the tool open source, available at sourceforge at:
http://sourceforge.net/projects/callplot
Callplot is written in Java. Please feel free to download, use, and provide improvements on this tool.
