I just uploaded a new release of WSPBuilder (1.0.1).

http://www.codeplex.com/Release/ProjectReleases.aspx?ProjectName=wspbuilder&ReleaseId=11603

This one has all the features I have been using over the last few months - In particular creation of a folder for copying to another server when you aren't deploying locally.

There is now also a template included for creating new WSPBuilder item templates. I'll write some more later on exactly how you do that.
