Warning: the material output by the following functions is delayed
112
in the pretty-printer queue in order to compute the proper line
113
breaking. Hence, you should not mix calls to the printing functions
114
of the basic I/O system with calls to the functions of this module:
115
this could result in some strange output seemingly unrelated with
116
the evaluation order of printing commands.

You may consider this module as providing an extension to the
120
115
<code class="code">printf</code> facility to provide automatic line breaking. The addition of
121
116
pretty-printing annotations to your regular <code class="code">printf</code> formats gives you

In case of interactive use, the system closes all opened boxes and
160
155
flushes all pending text (as with the <code class="code">print_newline</code> function)
161
156
after each phrase. Each phrase is therefore executed in the initial
162
state of the pretty-printer.<br>
