I recently posted some messages concerning Leo and Axiom to the
Leo developer forums at SourceForge:

Attached is a reply from Edward Ream, the developer of Leo. I am
planning to setup the kind of example that he requested, but I
would be glad for some help and discussion about this form the
Axiom developers.

Many thanks, Bill, for this letter.  Leo's noweb support could be a
lot better--Leo needs someone like you who is actually using both noweb
and Leo.  The present code is just 'made up': it kinda does the job,
but I would be happy to change any part of it to suit your needs.
Please do not assume that deep thought has gone into the present code

I don't remember why this is so, or even if there is a reason. Again,
I have no problem changing how this works.

I would like to suggest the following.  Please send me (or post on
Leo's wiki) a mockup of how you would like Leo to work with respect
to noweb.  Something like this:

- Example noweb source file (it can be as simple or detailed as
  you like)
- The proposed result of the import to noweb command.
- Any other proposals for how Leo could treat noweb more smoothly.

For example there are probably glitches in how Leo writes @file or
@thin trees containing 'real' noweb files.  It may be necessary for
Leo's write logic (in to treat real noweb files a bit
differently from Leo's other noweb markup.  I don't propose such a
change lightly, but it may be worth doing. The designation of a 'real'
noweb file could be done on the basis of file extension or as the
result of something like an @noweb directive.

Correct.  Leo's wiki pages are also sometimes useful, especially for
large hunks of code.  I like to give people a heads up on the SF
forums when I do something on the wiki.

Such questions are welcome.  Please start a new thread for them.
