+%
+% \section{Introduction}
+%
+% |elzcards| is a class meant to be an easy and flexible way to typeset business cards, index cards and flash cards, with its back side as an option. You must bother only by setting the paper size, margins and the design of your card\footnote{No predefined design is given; you must typeset your card.}. Everything else is done by |elzcards|.
+%
+% \section{Writing business cards}
+%
+% Please load the class. It hasn't options. Any option you specify will be passed to |article| class, in which |elzcards| is based on.
+%
+% \noindent {\color{RoyalBlue}|\documentclass{elzcards}|}
+%
+% \noindent Now I'll recommend you inserting the |geometry| package and setting the margins according to
+%
+% \noindent \hspace*{2em}\parbox{\textwidth-2em}{\begin{enumerate}[\bfseries 1.]
+%  \item the desired size of your card,
+%  \item the paper you'll use,
+%  \item the printable area of your printer.
+% \end{enumerate}}
+%
+% \noindent For example, for the default business card size (3.5 inches x 2 inches) in a letter paper, you may use:
+%
+% \noindent {\color{RoyalBlue}|\usepackage[letterpaper,landscape,vmargin={0.25in,0.25in},hmargin={0.25in,0.25in}]|
+%
+% \hfill |{geometry}|}
+%
+% \noindent After beginning your document, the only command you would use to produce the cards is |\MakeBC|, described below.
+%
+% \DescribeMacro{\MakeBC}{\color{RoyalBlue}|\MakeBC[*][*]|\oarg{xlen}\oarg{ylen}\oarg{zlen}\marg{front side design}\oarg{back side design}}
+% The only mandatory argument is the design of the card's front face. Everything you put inside |{}| will be stored in a box of size \meta{xlen} x \meta{ylen} and repeated in a grid until the page was filled.
+%
+% After closing the braces of the front side design of the card you can specify its back side design, if desired, as the last optional argument of |\MakeBC|\footnote{There is no need to specify the |twoside| option when loading the class even if you are writing twosided cards, but you must compile it twice.} (with square brackets).
+%
+% Both \meta{xlen} and \meta{ylen} are optional parameters to |\MakeBC|, and are \LaTeX{} lenghts; you can change the size of your cards specifying these lengths. Default values are, as stated before: 3.5 inches x 2 inches.
+%
+% The third optional parameter \meta{zlen} is also a length and has different meanings, depending on how you execute |\MakeBC|, i.e. starred or not starred. This will be explained just after clarifying what starred versions of |\MakeBC| are.
+%
+% Looking at the usage of |\MakeBC| we see the two optional stars, so we have three possible behaviors. Issuing |\MakeBC| without stars will print a grid of cards with segments and crosses as crop marks. The starred version |\MakeBC*| will print dots as crop marks, and the double starred version |\MakeBC**| will print lines between all the cards, like a grill. This may be useful also if you want the line as the border of the card, part of the design itself of the card\footnote{None of these crop marks will be added to the back side of a twosided document.}.
+%
+% Finally, the \meta{zlen} dimension represents the length of the segments when the standard cutting marks applies (no stars); also it represents the diameter of the dots (with one star), and the width of the line (with two stars). Its defaults values are: \meta{0.1mm}, \meta{1pt} and \meta{0.1mm} respectively.
+%
+%^^A Regarding the card's design, it's important to know that the |\unitlength| dimension, used in |picture| environment is defaulted to \meta{1mm}. This class relies on defining this length to \meta{1sp} to make its calculations, but it was set to \meta{1mm} inside the card to be used in |picture|, if you wish.
+%
+% \section{Writing index and flash cards}
+%
+% When writing other type of cards, like index cards and flash cards, you need to store all your cards in a stack and run the macro used to process them, that is |\MakeIC| (or |\MakeFC|, which is an alias to |\MakeIC|).
+%
+% \DescribeMacro{\Card}{\color{RoyalBlue}|\Card|\marg{front side design}\oarg{back side design}}
+% With this macro your add a card into the stack. You can add the number of cards you want with more instances of |\Card|. All these cards will be processed when you issue |\MakeIC| with the following syntax:
+%
+% \DescribeMacro{\MakeIC}
+% \DescribeMacro{\MakeFC}{\color{RoyalBlue}|\MakeIC[*][*]|\oarg{xlen}\oarg{ylen}\oarg{zlen}}
+% The syntax is the same as for business cards but without the business card's specific arguments because you've added all cards into the stack before. It accepts two optional stars and three optional lengths as parameters\footnote{Exactly the same as \cs{MakeBC} except there are no mandatory arguments.}.
+%
+% \section{Final words}
+%
+% In the same document you can write many different sets of cards. You can combine business cards with index cards in the order you want; also using different sizes of cards, different designs, cropping options and even changing the paper geometry with |\geometry|.
+%
+% If only one card has back side, the whole document behaves like a twosided document, i.e. it will swap horizontal margins and will have interleaved blank pages when a set of cards has only front side; this is the behavior of |twoside| option but you don't have to specify it by hand when loading the class.
+%
+% Take into account that this is \LaTeX, so you can define your own command and use it inside the |\MakeIC| and |\MakeBC|, like in the following example with |\mycenter|.
+%
+% \section{All-in-one example}
+%
+% The following example is included as |elzcards-example.tex|.
