Does the CLI expect simple filenames for merge? In other words, for multiple files, is it expecting something like--
$ calibre-debug --run-plugin EpubMerge file1.epub file2.epub book9.epub
I've got a directory with several epubs and with some fairly typical ebook names (by that I mean they are quite varied), as an example--
My ebook of all the planets_ John Smith.epub
How to make a souffle(part I) _ Web Recipes.epub
The Christmas Tree Story, Nothing Artificial.epub
I've tried many ways to get these oddly named files formatted so EpubMerge can handle, but I've hit a point where I'm not sure exactly sure what it's expecting.
