<p>
The details follow later, but basically policies can be set by either:
</p>
<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
Defining some macros that change the default behaviour: <span class="bold"><strong>this
is the recommended method for setting installation-wide policies</strong></span>.
</li>
<li class="listitem">
By instantiating a distribution object with an explicit policy: this
is mainly reserved for ad hoc policy changes.
</li>
<li class="listitem">
By passing a policy to a special function as an optional final argument:
this is mainly reserved for ad hoc policy changes.
</li>
<li class="listitem">
By using some helper macros to define a set of functions or distributions
in the current namespace that use a specific policy: <span class="bold"><strong>this
is the recommended method for setting policies on a project- or translation-unit-wide
basis</strong></span>.
</li>
</ul></div>
<p>
The following sections introduce these methods in more detail.
