I found an interesting tool for Java, called Macker
(http://innig.net/macker/), that I think would be nice to translate to
any language. The idea is to define the architecture in a file and let
the tool check if the code is structured accordingly or not, spitting
out errors and warnings.
A simple and useless example,
<?xml version="1.0" ?>
<ruleset name="Simple example">
<from class="**Print*" />
<to class="java.**" />
would give errors if any class having "Print" in its name tries to
access any class in the "java" package.
It wouldn't be all too difficult to build something similar with xref at
the bottom. This could be nice to have together with the tool that
Thomas Lindgren called for earlier, which analyzes the system and
detects the layers by itself.
