On the OON list I said I would be very interested to see what you have done 
with your library, and also said that "Boostify GluCat" is on my TODO list. I 
am still swamped with Math PhD work, but I would at least like to understand 
how much work would be needed to get GluCat into shape for Boost.

I posted the following to boost-users on 12 May but had no reply:

Back in January last year, I asked if there was any documentation which could 
help me to Boostify GluCat:
http://lists.boost.org/MailArchives/boost-users/msg02787.php
Since then I have been very busy, but in the next few months I may be able to 
find the time to get this done right, so I'm asking again:

GluCat is a new numeric template class library, hopefully destined for 
promotion to Boost. I would like to know where there is some documentation on 
how to:
1. Add concepts. Is there such a thing as a non-commutative multiplication 
concept? How do I check concepts?
2. Add numeric limits. Limits of U<T> would default to limits of T.
3. Add numeric promotion_traits. What are promotion_traits ? There is a 
discussion on ublas-dev mailing list about promotion_traits within uBLAS.
4. Add numeric type_traits. 

Also, is there a set of documented procedures which explain what is required 
for a library to be included in Boost?
