39 this package contains several functions to handle every label considering the
40 environment of the pdf file.

60 C<$marginLeft> Indicates how much left margin do you want in your page type.
62 C<$labelWidth> Indicates the width of the label that you are going to use.
64 C<$columns> Indicates how many columns do you want in your page type.
