<title>Friendly helpers
<abstract>
Some administration tasks require several steps. One must visit
various dialog in Linuxconf to achieve the desired goal. The gurus
are guiding you through a potentially complex scenario. Several
modules may be participating underneath.
</abstract>
<sect>Presentation
<p>
A helper is a sequence of simple dialog. Each dialog generally
present very few field, often, a single one. A lengthy explanation
introduce the fields. Once you have answered the question, you
hit the <em/Next/ button to go further, or the <em/Back/ button
to step to a previous dialog.
<sect>The map
<p>
At the top of the window, there is a map (graphic mode only).
It looks like a train station map. Each station correspond to a
dialog. The yellow station represent your current location in the
map.
<itemize>
<item>A white circle (blue outside, white inside)
represent an empty dialog.
Gurus may be used to configure something from scratch or review
a configuration. The white circle tells you immediately what may
be missing.
<item>A broken red circle represent a dialog with some invalid input.
The input may have been valid at some point but may become invalid
later while you change some other dialog along the path.
<item>A blue filled circle represents a filled dialog with valid input.
<item>A read line represents a meaningless path. The helper won't visit
the dialog along the path because they are not needed.
<item>A blue line represent a reachable dialog.
</itemize>
At this point, the map is not click-able with the mouse, but this is
coming.
