| 2 | 3-clause BSD License. You may use this project under either of these licenses

| 5 | We require contributions to be licensed under both licenses. The primary
 | 
|---|
| 6 | difference between them is that the Apache license takes care of potential
 | 
|---|
| 7 | issues with Patents and other intellectual property concerns. This is
 | 
|---|
| 8 | important to Subunit as Subunit wants to be license compatible in a very 
 | 
|---|
| 9 | broad manner to allow reuse and incorporation into other projects.

| 11 | Generally every source file in Subunit needs a license grant under both these
 | 
|---|
| 12 | licenses.  As the code is shipped as a single unit, a brief form is used:
