I wanted to play with flare, a flash based visualization library (also based in the prefuse visualization toolkit) I discovered in eTech. I despise Eclipse and IDEs in general so I aimed for a free, command line + Textmate based environment. This is how I got it working. Not that it’s hard, but here it is in writing to avoid common pitfalls (talk about niche posts). Note 1: I have no experience with Actionscript, Flash or Flex.
