Feature Request: read the list of files to process from specified file

[Originally posted by @drybjed as part of issue #1]
To manage multiple files easier, yaml2rst could read the list of files to process from specified file with syntax:

relative/input/file relative/output/file
relative/other/file /absolute/other/file

Or, .yaml2rst.yml file in the root of the role repository could be introduced with a YAML syntax and options like header/footer for templates and list of files to process in this role.

Is this something which could not be handled by a shell-script or a makefile?
