# A script that can automatically download videos from Edx
# Currently this is heavily tied to the way my Edx account and my computer is
# set up. It downloads by sending the the download url and download directory

# More info here: http://aria2.sourceforge.net/manual/en/html/aria2c.html#rpc-interface
# You can use http://ziahamza.github.io/webui-aria2/ to see download progress
# For now parameters, such as username, password, and which course to download 
# can be provided in the script
# I intend to make it more flexible

-- explaining why the original javascript code is so much shorter:
-- Javascript skips all error checking unless you perform explicit checks.
-- Haskell enforces all error checking unless you explicitly ignore errors.
-- I have thus implemented many wrapping functions whose purpose is to use
-- incomplete pattern-matching to ignore errors.
