DON'T BE A DICK PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
Do whatever you like with the original work, just don't be a dick.
Being a dick includes - but is not limited to - the following instances:
1a. Outright copyright infringement - Don't just copy this and change the name. 1b. Selling the unmodified original with no work done what-so-ever, that's REALLY being a dick. 1c. Modifying the original work to contain hidden harmful content. That would make you a PROPER dick.
If you become rich through modifications, related works/services, or supporting the original work, share the love. Only a dick would make loads off this work and not buy the original works creator(s) a pint.
Code is provided with no warranty. Using somebody else's code and bitching when it goes wrong makes you a DONKEY dick. Fix the problem yourself. A non-dick would submit the fix back.
