Rakefile

# Easy to use downloader Rakefile
# Add as many URLs you want in a file called download
# Requires youtube-dl - http://rg3.github.com/youtube-dl/
#
# echo URL >> download
# rake hq
#
# If you use a different source file, then run as follows:
#
# rake SOURCEFILE=some_other_file.txt
#
# Will use your credentials if you provide a proper cookies.txt file (Works
# with Firefox Export Cookies plugin -
# https://addons.mozilla.org/en-us/firefox/addon/export-cookies/ no luck with
# Chrome though)
#
# Downloads will go to downloads/uploader/*.mp4
# PS: I'm just lazy :P Modify as you see fit.
