Maneesh isn't on the techwr-l list, he replied to me for public posting, with more info on his comic, and the tools used to create it. See below message. I look forward to this tool!

Hi Lee

A very happy new year to you, and thanks for the nice words you dropped in
for the comics :)

And thanks for sharing the mailing list archive link.. it was very
heartening to hear such positive and encouraging thoughts from the folks.

Here is some additional information that you may share with the community:

The comics were written as a text file and converted into SVG images by a
javascript program I wrote. The steps are:
a) Write the comics as a text file. An example:
define <name> <type> <color> <mood> ..
define nn Server yellow happy
define dn Rack blue wink

panel Panel title..
nn: I am nn.. this is what I have to say.
nn to dn: the message text that goes from nn to dn
dn: My speech

panel Second panel title
mood nn sleep
color nn gray
nn: I am going to hibernate now

The benefit of a text format is, of course, ease of creation, modification
and review.
b) I wrote a javascript program that translates this text file into SVG
graphics. The rendering is done on a web browser, and I have used Raphael
library (
c) Once the SVG images are created, I used Apache's batik rasterizer to
convert them to PDF or JPEG.

I will, of course, release the source code in public, and produce
documentation on its usage soon (I am currently working on setting up a
website). My hope is that this text-formatted and web-based utility will be
easy and useful for the community at large. Secondly, the text format can
be stored in a versioning system, making it easy to collaborate and make

I look forward to your continued interest and feedback on other comics that
I plan to host soon.
