There is a new review of NAnt on TheServerSide.net.
i know it is in the articles section but it is a great review and HowTo more then an article.
dot get me wrong i like this review alot and it makes NAnt look very good.
i think that in an orgenized orginazation you can count on the NAnt methodoligy but in a non orgenized or an orginazation that has an SLC program with versioning, Change Requests and Bug tracking there will be a double work done in creating the NAnt XML build files.
if there was a solution that expand from the Requirements to the builds with a designated PM methodolegy like XP there will be a place for the abilities of NAnt solution.
I might build one like this when i finish the Visual Studio Tools for office.
