I created KCMD because I frequently use development boards which don't have a debugger. I like to be able to get up and running in a interactive way quickly. There were many iterations of attempts at a command processor before, and I eventually decided to do a better job. Then I decided that many people could also benefit, so I wanted to release it as open source. Writing the documentation was painful, but here it is.
I am Kevin Stokes. I can be reached via email at 
If you are using KCMD, I would like to hear about it. After all, I put lots of work into it, and especially the documentation.
That doesn't mean I will answer any email. If tons of people start asking me questions about KCMD I will have to start ignoring them. Nothing personal, but I hardly have any time to work on my own stuff already.
About me, I have been programming since I bought a Cosmac Elf (RCA 1802 CMOS processor) with money earned from paper route in the 1980's. I'm a physicist who ended up with a job as a software engineer. I had my own software company for a number of years; Now I work for the man. I run the website http://www.boldinventions.com where I document some of my hobby trials and tribulations.
I still remember portions of the cassette tape bootloader for the Elf I had to type into the hexidecimal keypad every time I booted. 256 bytes of bootloader I had memorized...
Because I'm not a very good programmer. However, I still think KCMD is useful.
I'm not releasing KCMD as open source because I'm a FSF zealot. I'm releasing the source because I don't think anyone would ever pay for it, and it was tons of work. I'd rather other people got to use it than just me.
That is not suprising at all. Write me about it and maybe I will make a new release. See the Who Are You section.
Oh, at this point I don't know if anybody will ever use it besides me. I may eventually put it on there if I think people are dying to help me keep it updated.
