Using qDebug to write to an external file

[qtUser500]

I would like to use qDebug in my application, and have it write to an external Log file. This way I can check for messages when the application is running in 'release' mode.

The version of Qt I am using is 3.3.5 (I know it is outdated et al, but my project is on it). The qDebug notes in QtAssistant doesn't provide information on writing to an external file. I would like to know if this is possible, and how to do it.

Thanks in advance.
