 %
-% You should typeset the design of the cards with one macro the package provides, followed by another macro to write them on paper. Macros used to manage business cards are not the same as for index/flash cards. Business cards are all equal, one design is repeated many times in a page, but index/flash cards are all different, so the macro to typeset index/flash cards manages a stack of cards. You should execute it many times as cards you have and all them will be stored to be processed when you have finished adding them. However, index cards and flash cards are in essence the same; the package provides macros for ``both'' cases but they behave the same. Macros aliases for flash cards were added for completeness.

 % \begin{itemize}

+% The package prints cropping marks to guide the cutting of the cards; these cutting marks may be crosses inside the printed area, segments outside the printed area, dots inside and outside the printed area, or continuous lines. You can change the length of that segments, thickness of lines, size of dots and colors of all these cutting marks.
+%
 % \subsection{Typesetting the cards}
 %
+% You typeset (compose) your cards using macros described in this subsection; your cards will be stored internally in boxes or stacks and will be processed later by issuing the appropriate macro (described in the following subsection). Only two commands: storing cards, and later processing them.

What you write as the first argument (with braces) will be the card's front face design, and its second -optional- argument (with square brackets) is the card's back side\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 your document twice.}. Everything you put inside |{ }| and inside |[ ]| will be stored in a box and repeated in a grid until the page has been filled.

 %
-% 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 in |\documentclass|.

 %
 % Take into account that this is \LaTeX, so you can define your own commands and use them inside the |\BusinessCard| and |\IndexCard| macros, like in examples with macro |\mycenter|.
