what's the problem? that the readme doesn't match the code? I'd change the readme

Sorry about that, I thought it was easier to understand.

The problem is that when using the parameter as it was described at the readme file ( output ), the parameter was obviously ignored (as the code is expecting another parameter). However, when trying to use the parameter that the code expected ( file ), it doesn't work either (I can't remember if it is throwing an exception or what is the behaviour).

I performed this fix a time ago so I'm not sure what the actual problem was. Moreover, today I couldn't find what the causes may be. If file parameter works fine, you should definitely fix the documentation, not the code.
