+% Instructions:
+%
+%    Read the documentation for the lineno package.
+%
+%    The vertbars package takes the same options as the lineno package.
+% In particular, the switch and switch* options control which side
+% of the page any bars will be printed. The package automatically
+% calls the lineno package, so you just need:
+% \usepackage[...]{vertbars}
+%
+%    The package provides one environment, namely the vertbar environment.
+% The vertbar environment is equivalent to the linenumbers environment
+% except that a vertical bar replaces the line number. Text paragraphs 
+% within a vertbar environment will be marked with a vertical bar in 
+% the margin. Nested environments generate multiple marginal bars.
+%
+%    The width of the bars is controlled by the value of \barwidth, which 
+% is initialised to 0.4pt, and can be changed via \setlength.
+%
+%    The horizontal seperation between adjacent bars is controlled by
+% the value of \barspace, which is initialised to 0.5\linenumbersep, and can
+% be changed via \setlength. (\linenumbersep is a command from the
+% lineno package that controls the spacing between line numbers and the
+% text body).
+%
+% NOTE: Bars can only be applied to complete paragraphs. For bars 
+% between arbitrary points, use the changebar package. Any limitations
+% of the lineno package apply equally to the vertbars package.
