Wow, seems like I was forcing an open door. I should have examined the SAL
database more carefully. Why didn't you put your package into the freshmeat

Well, we have compatible licenses, and it shouldn't be very hard. BTW, I see
that Peter Rice is working at LION Bioscience, and our group has a
collaboration with this company -- interesting. One thing about my programs
is that I try to keep them as ANSI and lightweight as possible. I will
definitely download your developer tree and look at the source.

Why, yes, quite easily. Basically, it is a very simple thing: you have
three windows -- stdin, stderr and stdout. You can save or modify them.
Then, you have a sort of database holding information about my command-line
tools programs: names, options, short descriptions of the programs and
options etc. Right now it is hard-wired into the program, but the next
version will just read a configuration file which will be much more flexible.

You can run any program included in the "database" or issue an arbitrary
command -- you have a command history (stored before exiting) and I plan to
extend it to build little "macros" which will be in fact just /bin/bash

Apart from that, there are two graphical utilities: one for showing simple
GC content graphs (which I did for learning to program gtk+) and one for
showing 3D graphs of arbitrary data (which I did because I needed to
visualize DNA structures). 

Unfortunately, Arka is not portable. This is gtk+, and though there is gtk+
in Windows, there is also a lot of Unix-specific code in my program, so
basically Arka is Linux-specific.
