+% HELP FOR SETTING UP PARBOXES
+% \parbox[position][height][inner-pos]{width}{text}
+% The \parbox has two mandatory arguments:
+%     width - specifies the width of the parbox, and
+%     text - the text that goes inside the parbox. 
+% LaTeX will position a parbox so its center lines up with the center of the text line. The optional position argument allows you to line up either the top or bottom line in the parbox (default is top).
+% If the height argument is not given, the box will have the natural height of the text.
+% The inner-pos argument controls the placement of the text inside the box. If it is not specified, position is used.
+%     t -- text is placed at the top of the box.
+%     c -- text is centred in the box.
+%     b -- text is placed at the bottom of the box.

+% DEPARTMENT OR SCHOOL
+% This just sets the size of the box to the right of the logo, and the size of the vertical line.  The vertical line is set by the size of the first numerical argument of the \parbox command.
+%
+% In the future, the "From" address might be better set using "tikz".

+%%%%%%%%%%%%%%%%%%%%%  Signature line  %%%%%%%%%%%%%%%%%%%%%
+
+% Set your signature line here.
+% One can add a signature image in a PDF file using the following code; this requires a file called "signature_block.pdf" to be installed in the same folder as the .tex file.  The vertical spacing (\vspace) and the scaling will have to be adjusted to get things to look correct for your particular signature image. Alternatively, comment out the following line in favor of the one labeled "[[Alternate]]" if you want to sign a paper copy of the letter.

+% This block sets up the address on the right-hand side of the header. 
+% The following lines just compile the information you set up into the LaTex letter variable "address" for later use.

+%%%%%%%%%%%  DATE  %%%%%%%%%%%%%%%%%%%%%%%%%
+
+% If you want a date different from the current date, comment out the next line in favor of the line labeled "[[Alternate]]".  The ``\vspace{10mm}'' just moves the date down a tiny bit so it doesn't interfere with the header.  This can be adjusted to your preference.
