This has been very helpful so far! I get an error when I try and run one of 
your commands, though. I am trying the numbered files method, with all 
chapters in a folder, numbered like so.

0010-intro.md

0020-part1.md

0030-part2.md.

With all the files in the directory, I run the following command.

pandoc -s -o merged.odt *.md

The error I get is,

pandoc: *.md: withBinaryFile: invalid argument (Invalid argument)

Any ideas on what could be the problem with the above? All of your other 
suggestions have worked so far!
