[jsapigen-devel] [PATCH 3/3] Add basic usage examples
|
From: Vincent S. <vi...@de...> - 2012-07-02 11:50:26
|
From: Vincent Sanders <vi...@co...>
Add some examples partially based on examples from the manual. The common
startup code may be compiled on any spidermonkey API
I would have MIT licenced them all but I did cut and paste from the manual
examples so I had to stick to your licence.
