Pooling efforts is the only thing that makes sense.  But perhaps that 
should be on a wiki page specifically dedicated as a draft Guile API 
page, rather than as your personal page.  I don't feel good editing 
other peoples' personal pages.

First, though, I'm setting up my development environment, and trying to 
get over a bout of some kind of mild stomach flu.  And I'll have to get 
some kiind of feel for the system's internals before I really feel free 
to start documenting it.  Except for maybe a bit of personal 
development diary and function descriptions that start like "Could this 
possibly be the function that ..."

And it's more than just API that's needed.  There's also things like 
how to run gnucash-env to run scheme code on its right 
environment (as mentioned in another post on this forum; thanks, 

My personal development log will probably tell me the unobvious about 
what needs to be documented.

As for your draft declarative report, I'm not ready yet.
