#This script is a barebones way to see what is in my inbox
#and to read individual messages.
#Sort of a poor man's mail reader (but no sending emails).
#It makes no changes to INBOX.
#Mostly to work around issues reading mail on my Moto Q
#I added something to only show a certain number of characters
#at a time on screen, sort of a poor man's more.
