About Open Source Licenses
Open source licenses are licenses that comply with the Open Source Definition
in brief, they allow software to be freely used, modified, and shared. To be
approved by the Open Source Initiative (also known as the OSI), a license must
go through the Open Source Initiative's license review process.

The OSI maintains a FAQ, which includes a lot of useful background on open
source licensing, including:
Can Open Source software be used for commercial purposes?
What is "free software" and is it the same as "open source"?
What is "copyleft"? Is it the same as "open source"?
What is a "permissive" Open Source license?
