help building ipk packages

[Nicolas Laurance]

hi community gurus,

I've done my homework, at least I tried to, reading through the wiki and 
elsewhere

http://lists.openmoko.org/nabble.html#nabble-td1084542

still building a simple package remains a mystery to me

following the instructions of the wiki, regarding the setup of openembed
the monotone command always fail (at least 6 retries)::

$ mtn --db=OE.mtn pull monotone.openembedded.org org.openembedded.dev
mtn: doing anonymous pull; use -kKEYNAME if you need authentication

However, MY QUESTION IS :

how can I build an ipk package out of a project source file ??

please, can someone, give a simple example, choosing a running program 
of some kind, of the steps to follow
the bb recipe and the procedure to produce a small ipk

All I've found is scarecely documented, and is concerning a global image 
for the moko.

many, many thanks
