import Kindle "My Clippings.txt" into separate markdown files per author

	import re
	import sys
	"""

	This is a helpful little script for importing your kindle underlines from books.
	Because I read multiple books at once, my underlines get mixed up and out of order.
	This script untangles my underlines and puts each book into a nice neat markdown file.

	Things to be wary of:
	- Author names should be adjusted to be 3 words or less (including hyphenations)

convert images to vectors

	# mkbitmap parameters:
	# -f n == Apply a highpass filter to the image.The parameter n is a radius (in pixels) which corresponds approximately to the size of details which should be preserved.
	# -s n == Scale the image by an integer factor n>0.
	# -3 == Use cubic interpolation when scaling to a higher resolution.
	# -t n == Set the threshold grey value for bilevel conversion.

	# TODO
	# - check if we're parsing raw clippings into
	# - a new author file

Flowcharts from Notion DBs

	# WHAT IS IT
	# This is a hacky little script to generate Mermaid flowcharts from Notion page relations across databases

	# TO USE:
	# - Grab your Notion API key and stick it in "token"
	# - Make sure you've allowed your databases access via "Share" (for each database!)
	# - Run the script, copypasta from command line into a code block

	# TO DO:
	# - Add filtering of relations (a kind of config)
