I have a need to merge or join a number of audiofiles into one bigger file.

Is there any plans to implement that in the commandline converter?
Like define one input file and join it after the outputfile, or define 2 inputfiles to be joined into one new file. Then the process may be repetead to add more files together.

Or is it already available in the product? I have not found it. PLease let meknow if I have missed it.
