# LaTeX formatting issues

I am about to submit an article for review, and had to format in a special way. Here is a quick summary of what I did:

No paragraph indents:

﻿\setlength{\parindent}{0in}
but a single line between:
﻿\usepackage{parskip}
Left text justification:
﻿ \begin{flushleft} ... ﻿ \end{flushleft}
Double spacing:
﻿\renewcommand{\baselinestretch}{2}
