* Dear Contributor,
|
|

|
|
* In order to ensure this project remains completely free and unencumbered by
|
|
* anyone's copyright monopoly, it is advisable that you dedicate your code-base
|
|
* contributions to the three licensing terms above. This removes any possible
|
|
* ambiguity as to what terms somebody might have thought they were contributing
|
|
* under, in case of a future dispute. These concerns are not unique to public
|
|
* domain software. Most large, established open-source projects have a
|
|
* Contributor License Agreement (CLA) process, of varying degrees of formality.
|
|
*
|
|
* Please add yourself to the list below before contributing.
|
|
* Thanks.
