[Koha-devel] Make koha dance!

[Marc Chantreux]

hello koha people,

As Paul said in his last message, we try to know if it's possible to
introduce a clear layer structure in koha (actually: we think it's
possible).

the most important layer is the MODEL and we would like to use very
modern perl OO paradigms (as MooseX::Declare) to clean it. The problem
there is that Moose is a bottleneck at start time so CGI scheme must
be removed first. It leads us to the CONTROLLER part which is the part
where we can introduce an MVC framework.

So we tried to make koha run on top of Dancer ... this is my report on
the WIP, we hope you'll enjoy:
