* DESCRIPTION

These environments allow page breaks inside framed boxes.
They include a few examples (shaded box, box with a wavy 
line on its side, etc.)

See also macros/latex/contrib/other/misc/framed.sty.

* USAGE

In the preamble: 

  \usepackage{boites,boites_examples,graphicx}

Before using the various environments:

  \bkcounttrue:  the lines will be numbered
  \bkcountfalse: the lines will not be numbered

Boxed text with a title:

  \begin{boiteepaisseavecuntitre}
    ...
  \end{boiteepaisseavecuntitre}

Text with a double vertical line on the left and a number 
(17, in this example):

  \begin{boitenumeroteeavecunedoublebarre}{17}
    ...
  \end{boitenumeroteeavecunedoublebarre}

Text with a wavy line on the left:

  \begin{boiteavecunelignequiondulesurlecote}
    ...
  \end{boiteavecunelignequiondulesurlecote}

Shaded box:

  \begin{boitecoloriee}
    ...
  \end{boitecoloriee}

If you wish other kinds of boxes, have a look at boites_examples.sty
and feel free to adapt the macros.
