%Block Quote Spacing (\doublespaced or \singlespaced)
\newcommand{\blockquotespacing}{\doublespaced}
%The blockwuote environment has two options, \poetry or \prose (it defaults to \prose).
%If your prose blockquote has multiple paragraphs, then begin the environments as you would would a new paragraph (i.e. with an empty line between the text and the environment).
%This will tell blockquote to indent the first line of each paragraph in your block a further .25 inches.
