GitHub reminder is a bot that parses issues looking for dates and applies labels according to them.
The bot simply looks for lines like deadline is June 20th 2015 and every day applies the most
adequate label to it.
The most adequate label is chosen from the labels already exisitng in the repository following
the syntax deadline < 30, deadline < 5 etc.
If the deadline is on 31 days or more no label is applied, if it's in between 6 days and 30
the deadline < 30 will be applied. Finally for 5 days or less deadline < 5 will
apply.
