Hello,

Due to the fact that oggz-comment demands that all the metadata is present on 
the command line i've written a bash scrip wrapper that passes through all the 
configuration, but reads the metadata one line at the time and puts it in the 
correct place. Please use it however you want.

               - Volodya
