I want to run pofilter only for some po files and not all in the directory structure (like a/xx.po d/xx.po). But only one --input parameter is considered. (I can give many --exclude parameters which are all considered, but this gets too complicated with many files.)
So I suggest to support several input parameters for pofilter (and other commands).

How

To change this, inputoption must have action="append" in

More info

The code supports array for input:

I monkey-patched pofilter and it runs as expected.

• the input files or directories are used
• to create the output directories, the common ancestor directory of the input is used as base

Other commands could profit as well from this idea. (All those accepting a directory as input.) I did not check all commands, but converters (checked po2tiki and po2xliff) do, pocompile and poclean do, ...
I do not get if pomerge does, I do not understand the message.

I am happy to send a patch, but I would like to know for where because I do not have experience with most of the commands.
