"""Creates a tarball with V8 sources, but without .svn directories.
|
||
|
|
|
||
|
|
This allows easy packaging of V8, synchronized with browser releases.
|
||
|
|
|
||
|
|
Example usage:
|
||
|
|
|
||
|
|
export_v8_tarball.py /foo/bar
|
||
|
|
|
||
|
|
The above will create file /foo/bar/v8-VERSION.tar.bz2 if it doesn't exist.
