Python templates don't honor the project.license property setting. They always use the value of "default". The
workaround given below for Ruby templates works for Python as well.

Copied from Issue # 148285 Re: Ruby templates. 

According to http://platform.netbeans.org/tutorials/60/nbm-filetemplates.html#license, I should be able to set
project.license in the project.properties file to make the template include a different license than the default.

I have followed the instructions in the above tutorial for a Java project and see that it works. When I try it with Ruby
templates, the project.license is never read and the license is always the default. If I have the template print out
project.license it prints "default" and not "ruby".

Workaround: replace ${project.license} with ${license} and put 
license=ruby in the User Configuration Properties > User.properties template.

However, if you are sharing the project, this won't affect other uses. There should be a way to set the license for a
project.
