space at end of line?

[floitsch, 2014/03/31 12:53:26]

Should we generate "precompiled.js" or generate to the output-file that is

That is, should --out=foo.js be the precompiled file, when using --csp ?

[Johnni Winther, 2014/04/01 08:20:21]

Removed.

[Johnni Winther, 2014/04/01 08:20:21]

Done.
