NewPodFeed is a software to make creating new iTunes-compatible RSS feeds for podcasts easy.
The binary program is just a jar file in a .zip file (a little redundant, eh?) Just extract the jar file, and in Linux, providing you have the right version of Java installed and it's in your path, you should just be able to type "java -jar NewPodFeed.jar" on the command line.
The program is being developed with the NetBeans IDE.
How can I help?
If you really wanted to help, the program is in some serious need of some documentation. The code isn't even commented yet. These are things I will eventually get to, but if you want to help out with them, feel free. Also, this website is obviously pretty plain. If you want to help out with that, be my guest.
