# encoding: UTF-8

# remember to compile with Transformations...Convert Plain Text to Paragraph Spacing
# small script to convert my style of writing markdown(ish) in Scrivener to dokuwiki
# allows you to use - with no indent instead of * indented two spaces for bullet list
# (can use tabs to increase indent)
# b. at the beginning of a line wraps line in blockquote
# uses h1. h2. for headings with DW plugin, can be modified to support classic DW headers
