%*			    InfoMap Environment				    *
%*									    *
%* Description:								    *
%*	The infomap environment is a modified description environment in    *
%*	which the label is set off from the text as a signpost.  The	    *
%*	signpost is implemented in a \parbox to allow for a multi-line	    *
%*	label.								    *
%*									    *
%* Syntax:                                                                  *
%*	\begin{infomap}  \item[label] text  \end{infomap}		    *
%*									    *
%* Where:								    *
%*	label	is the text to be placed in the Signpost at the current	    *
%*		left margin.						    *
%*									    *
%* Note:								    *
%*	The signpost is implemented as a \parbox set in a \raisebox which   *
%*	has a depth of 0pt.  This is necessary to make a multi-line sign-   *
%*	work correctly, but occasionally, you will need to add extra	    *
%*	vertical space if the signpost occupies more lines than the text.   *

%*			    Note Environment				    *
%*									    *
%* Description:								    *
%*	The note environment is a modified version of the quote environment.*
%*	It is distinctive in that it has a centered title for the note	    *
%*	prior to the beginning of the text.  The title may be specified,    *
%*	using the optional argument.  If no title is specified, the title   *
%*	"Note" is used.							    *
%*									    *
%* Syntax:                                                                  *
%*	\begin{note}[title]  text  \end{note}				    *
%*									    *
%* Where:								    *
%*	title	    is the text to be used as the title.  If not specified  *
%*		    "Note" is used.  The title is centered above the text,  *
%*		    in boldface.					    *
%*									    *
%* Note:								    *
%*	It is possible for the title and text of a note to be separated	    *
%*	across a page break.  So far, I haven't been able to discover a	    *
%*	fool-proof way to prevent this from occurring, so check the output. *

%* Description:								    *
%*	The \ctl command is used to place a representation of a control	    *

%*									    *

%*			    ULine Command				    *
%*									    *
%* Description:								    *
%*	The \uline command is used to underline text.  Unlike the	    *
%*	\underline command, \uline provides the user with the ability to    *
%*	control the thickness of the line.				    *
%*									    *
%* Syntax:                                                                  *

%*			ForceRightPage Command				    *

%*	which follows to appear on a right-hand page.  The blank page will  *
%*	contain an optional, centered message.				    *

%*		    is used.						    *
%*									    *

%* Description:								    *
%*	The \input command is a variation of the standard LaTeX command of  *
%*	the same name.  It reads in an external file.  It differs from the  *
%*	normal LaTeX command in that if the specified file is not found,    *
%*	the routine displays a message and continues, rather than prompting *
%*	for a new file name.						    *
%*									    *
%* Syntax:                                                                  *

%*									    *
%* Where:								    *
%*	file	    is the file specification of the input file to be read. *
%*		    By default, the file has the file type ".tex" unless    *
%*		    specified otherwise.  If the file is not found in the   *
%*		    current default directory, it will be searched for in   *

%* Description:								    *
%*	The screenpix environment is used to display the image of a screen  *
%*	in a document.  A curved line is drawn at the top, which represents *
%*	the beginning of the screen.  After the verbatim text, another line *
%*	is drawn at the bottom to represent the bottom of the screen.	    *
%*									    *
%*	Lines up to 80 characters long may appear.  You should place a	    *
%*	leading space at the beginning of each line, so that the text will  *
%*	not overwrite the curved lines.  Since tabs are not expanded in	    *
%*	verbatim mode, they should be explicitly converted to spaces.	    *
%*									    *
%* Syntax:                                                                  *

%*	counting the REQUIRED leading space on each line.		    *
%*									    *
%* Note:								    *
%*	This environment assumes that a text width of 6 inches is available *
