pre-existing folder for article EPUB conversion will be eliminated without
asking user permission, all output that except the .epub and .log files
will be removed, and image files in a custom directory are not being used.
Unlike the other input modes, Batch Input Mode output is always relative to
the batch directory rather than the working directory of oaepub execution.
Batch Input Mode has default epubcheck behavior, it will place a system
