# Remove the manuscript images folder before creating book.txt
# Scrivener will probably have wiped it out already, but let's make sure.

# Get a sorted list of all files in the manuscript and add them to book.txt.

# Copy the images directory into the manuscript
# Because Scrivener wipes it out on export.

Some notes:

• This is a very purpose driven script. If you're not taking text exported from Scrivener and publishing it in Leanpub this doesn't really get you much. But the pattern might be useful.
• On line 12 we are stripping off the initial ./ because Leanpub doesn't need it.
• I could probably make line 11 more extensible by telling it to look for anything in an array and skip those. But I deliberately chose not to optimize early. And it is killing me.
• Written for python 2 because I'm lazy. I know Python 3 has easier ways to do some of this stuff, I just don't have it installed on all my machines.
