| The details follow later, but basically policies can be set by either: |
| </p> |
| <div class="itemizedlist"><ul type="disc"> |
| <li> |
| 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> |
| By instantiating a distribution object with an explicit policy: this |
| is mainly reserved for ad hoc policy changes. |
| </li> |
| <li> |
| By passing a policy to a special function as an optional final argument: |
| this is mainly reserved for ad hoc policy changes. |
| </li> |
| <li> |
| 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> |
