Free e-book: Programming Add-ons for Blender 2.5: "Programming..." it is an e-book, published freely on Creative Commons license. I am showing there, how to adapt popular Open Source IDE - Eclipse - for developing Blender scripts. This is merely an introduction to this subject. It is intended for the readers familiar with Python and Blender 2.5 on the average level, at least.
