+% Environment "wrapfigure" to manually place a figure at the side
+% of the page and wrap text around it.
+%
+% \begin{wrapfigure}[36]{r}{3in} <figure> <\caption> etc. \end{wrapfigure}
+% -- - ---
+% [number of narrow lines] {left or right} {width of figure}
+%
+% Usage:
+% This is a different type of *non-floating* figure environment for LaTeX.
+% A figure of the specified width appears on the left or right (as specified)
+% of the page. LaTeX will try to wrap text around the figure leaving a gap of
+% \columsep by producing a number of short lines of text. LaTeX calculates
+% the number of short lines needed based on the height of the figure plus
+% the length \intextsep. You can override this guess by giving the optional
+% argument specifying the number of shortened lines (counting each displayed
+% equation as 3 lines). Cautions:
+% o Wrapfigure should not be used inside another environment (e.g., list)
+% o It does work in two-column format, but that would be silly.
+% o Since it does not float, it may be out of sequence with floated figures.
+% o The automatic rules (lines) that may be placed above or below floats
+% are ignored here. You must insert the rules manually.
+%
+% Placement:
+% LaTeX will not move a wrapfigure to the best place, so it is up to YOU
+% to position it well. Any changes to the document can ruin your careful
+% positioning so wrapfigures should be positioned just before printing a
+% final copy. Here are the rules for good placement:
+% o The environment should be placed so as to not run over a page boundary.
+% o Only ordinary text should have to flow past the figure; no section
+% titles please. Equations are acceptable if they fit.
+% o It is convenient to give \begin{wrapfigure} just after a paragraph has
+% ended. But if you want to start in the middle of a paragraph, you must
+% put the environment between two words where there is a natural linebreak
+% (like "must" and "put" above).
