=head1 Elements |
|
|
|
=head2 Element: helpiconX<helpicon, helper element> |
|
|
|
Helpicon elements add a help icon at the current location. |
|
Example: |
|
|
|
<helpicon file="Help"> |
|
General Help |
|
</helpicon> |
|
|
|
In this example will generate a help icon to the Help.hlp url with a |
|
description of 'General Help'. The description is not required and if |
|
left out (Example: <helpicon file="Help" /> only the icon will be |
|
added.) |
|
|
|
=head3 Localization |
|
|
|
The description text will be run through the normalize_string function |
|
and that will be used as a call to &mt. |
