Is it possible to display checkboxes with InstallBuilder?

InstallBuilder is able to display checkboxes in the parameters. To do so, you need to define a <booleanParameter> specifying <displayStyle> to be either checkbox-left or checkbox-right. The snippet of code below does it:

<booleanParameter>
  <name>perform_action</name>
  <description>Would you like to perform 'action'?</description>
  <title>My checkbox</title>
  <displayStyle>checkbox-left</displayStyle>
</booleanParameter>

You can group different boolean parameters under a <parameterGroup> so that different checkboxes are displayed in the same installation screen.
