<div class="paragraph"><p>Explorer are small shell scripts, which will be executed on the target
|
|
host. The aim of the explorer is to give hints to types on how to act on the
|
|
target system. An explorer outputs the result to stdout, which is usually
|
|
a one liner, but may be empty or multi line especially in the case of
|
|
type explorers.</p></div>
|
|
<div class="paragraph"><p>There are general explorers, which are run in an early stage, and
|
|
type explorers. Both work almost exactly the same way, with the difference
|
|
that the values of the general explorers are stored in a general location and
|
|
the type specific below the object.</p></div>
|
|
<div class="paragraph"><p>Explorers can reuse other explorers on the target system by calling
|
|
$<em>explorer/<explorer_name> (general and type explorer) or
|
|
$</em>type_explorer/<explorer name> (type explorer).</p></div>
