] | I'm new to NAnt but have some experience with Ant and CruiseControl.
What I want to do is have my SVN project include all tools needed (like NUnit and Mocks etc) so I can check out onto a fresh machine and build. This strategy is outlined by J.P Boodhoo [here.](http://blog.jpboodhoo.com/NAntStarterSeries.aspx)
So far... | This shouldn't be a particularly difficult excercise. We do some fairly similar stuff on one of my projects since half of it runs on Java using Ant to run relevant targets, and the other half is .Net (C#) for the UI. The projects get run on windows machines for development, but the servers (Java) run linux, but in the ... |

**First:**
for real logging, use a modern logging package like log4j or java's own built in logging. Don't worry about performance so much, the logging level check is on the order of nanoseconds. (it's an integer comparison).

What you should probably do instead is unravel the thing in your *view* code, so it's just a matter of iterating over (in|de)dents in the template. I think I'd do it by appending indents and dedents to a list while recursing through the tree and then sending that "travelogue" ... |
