As promised, here is the info that you need to start playing with Duda:
1) Clone DudaC (Duda Client Manager):
# git clone git://git.monkey-project.com/dudac
2) Clone Duda Examples
# git clone git://git.monkey-project.com/duda-examples
3) Go into DudaC directory and start the Hello World example:
# cd duda
# ./dudac -g
# ./dudac -f -w /path/to/duda-examples/001_hello_world
4) Now open your browser at: http://localhost:2001/hello/
Comments:
------------------
- When you run 'dudac -g', it will download Monkey and Duda sources
from their respective GIT repositories and set the development
environment for you. You only need to run that command once unless you
want to update your local copies if some patches were applied to the
master repositories
- The '-f' flag means 'fast-run', so it will not try to build Monkey
again for the web service, instead it will just perform the setup
- The '-w' flag specifies where the web service sources are located,
it will check the code, compile, configure the web server and launch
the web service.
The source code of hello world looks like this:
#include "webservice.h"
DUDA_REGISTER("Duda I/O Examples", "Hello World");
void cb_hello(duda_request_t *dr)
{
response->http_status(dr, 200);
response->printf(dr, "Hello World!");
response->end(dr, NULL);
}
int duda_main()
{
map->static_add("/", "cb_hello");
return 0;
}
I am still working in some formal documentation, but you can see a
draft of the API available here:

Feel free to write to this mailing list with your questions,
cheers,
