# Converts Day One exported notes to `enex` for Evernote importing
# Not complete
# It only exports:
# - title (assumed as the first line of the content starting with `# `)
# - content (rest of the content)
# - tags
# - created
# - updated

# NOTE: Apparently Tags are not imported. There seems to be a problem on the Evernote side.
# I exported a note with tags from Evernote, and then reimported it and the tags were gone.
