%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% You can have multiple style options the legal options ones are:
%
%   centered    the name and address are centered at the top of the
%               page (default)
%
%   line        the name is the left with a horizontal line then 
%               the address to the right
%
%   overlapped  the section titles overlap the body text (default)
%
%   margin      the section titles are to the left of the body text
%               
%   11pt        use 11 point fonts instead of 10 point fonts
%
%   12pt        use 12 point fonts instead of 10 point fonts
%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%   Commands
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%   \Resume     prints the word resume but typeset nicely
%
%   \newsectionwidth{dimen}
%               defines the amount of space the labels extend
%               into the left margin.
%               DO NOT TRY to change any of the dimensions
%               yourself.  You will probably confuse the style file.
%
%   \name{text} defines your name
%
%   \address{text}
%               defines your address
%               this can be called twice if you have two addresses
%               use \\'s to indicate where either line breaks or
%               comas should go
%
%   \opening    this prints your name and address at that spot
%               this is not normally needed, as \begin{resume}
%               does this but is provided just in case you need
%               to do something odd
%
%   \begin{resume} ... \end{resume}
%               all of the resume should go inside of this
%               environment
%
%   \section{text}
%               This prints 'text' in the left hand margin.
%               Its exact placement depends on what the style 
%               options has been set to. (overlapped or margin)
%               You should use \\ to start a new line.  If the
%               style option is margin, the \\ is converted
%               to a space.
%               To use this in any of the list environments, put
%               the \section after the \item[] but before the 
%               text.
%               Eg.
%               \begin{itemize}
%               \item\section{text}
%               text
%               \end{itemize}
%
%   \begin{ncolumn}{n} ... \end{ncolumn}
%               creates a tabular environment with n equally
%               spaced columns.  Separate columns by & and
%               end them with \\
%
%   \begin{position} ... \end{position}
%               this is used to print a job description.  There should
%               be only one job description in it.  Information
%               related to the job (such as title, dates...) will
%               be printed.
%
%   \begin{format} ... \end{format}
%               used to change the default format for the position
%               environment.  Within it the recognized commands are:
%               \title{option}
%               \employer{option}
%               \location{option}
%               \dates{option}
%               \body
%               \\
%               where option is one of l,r,c standing for left, right, center.
%               The format will eventually be used to make several
%               tabular environments and you are defining the number of columns
%               and the placement of text within the columns of the tabulars.
%               Each row is terminated by a \\.  Any number of options can 
%               be on a line, they will each be set in their own columns.
%               Any of the options except \body may be left out.
%
%               Eg.
%               \begin{format}
%               \title{l}\employer{r}\\
%               \dates{r}\\
%               \body\\
%               \location{l}\\
%               \end{format}
%
%               In this example the title and employer information
%               are set in 2 columns left justified and right justified
%               respectively.  Then the date is set right justified.
%               Then the body is set.  Then the location is set left
%               justified.
%
% \employer{text}
% \title{text}
% \dates{text}
% \location{text}
%               declare text for the next invocation of the position
%               environment
%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

% THINGS TO DO
%
% add lm,rm options to format style to allow things to be placed
% in the left or right margin respectivly
%
% add capability so that \body doesn't have to be proceeded (followed)
% by a \\ allowing part of the description (eg. location) to be the
% first (last) thing of the body
%
% clean up the list building procedures
%
% write docs to tell people how to use this

% this is used to define how the position environment should
% formated.
%
% \begin{format} positioning text \end{format}
% where positioning text may be
%  \employer{pos}
%  \location{pos}
%  \dates{pos}
%  \title{pos}
%  \body            (for the body of the position environment)
%   where pos is 
%     l for left
%     r for right
%     c for center
% use \\ to break the line
% you don't have to use all of the options.
% on any one line, you should indicate what you want on that line
% and where it should go within its column.
% eg.
% the following prints the employer in the left with the location
% centered within that its column.  It then prints the date on the
% right.  Then it prints the body of the position environment. Then
% it prints the title centered within its column; as there is only
% one column here it is really just centered.
