<p class="commentary firstcommentary"><a id="SP1" class="paragraph-anchor"></a><b>§1. </b>The Devices plugin does just one thing: it applies an indicator property
|
|
to things of the kind "device". This used to be accomplished by the Standard
|
|
Rules in a clumsy sort of way (with a direct I6 code injection), but in the
|
|
age of Inter we want to avoid that sort of tomfoolery.
