# Borrowed from activesupport, but without the :try method
class String
# Strips indentation in heredocs.
#
# For example in
#
# if options[:usage]
# puts <<-USAGE.strip_heredoc
# This command does such and such.
#
# Supported options are:
# -h This message
# ...
# USAGE
# end
#
# the user would see the usage message aligned against the left margin.
#
# Technically, it looks for the least indented line in the whole string, and removes
# that amount of leading whitespace.
