Simple donationware license?

[petersphilo]

Hello all,
i'd like to publish some software as donationware..
i'm trying to find a sort of 'boilerplate' license i can use, could anyone point me in the right direction?
Thank you!

When you say 'donationware', is it a pay what you want (or nothing)? Or is there a minimum set.

If the latter, it's not donationware. If so, you can just use any free license and add that donations are welcomed but not required.

Thank you for your answer!
Definitely the former..
Here's what i'm thinking of putting in the code, along with a donate button (the 'software' is a php module for HumHub - an open source social network):

/**

PS: note that this is only visible to administrators, so only they would see the donate button..
