[Phpwebsite-developers] Adding content variables

[Shaun M. <sh...@ae...>]

Is there an accepted way in which I can add a content variable on 
upgrading a module?

I've split the announce module so that it's got three now instead of 
two so that the list of current announcements on the home page can be 
in a different box to the announcement.

Before it was

CNT_announce
CNT_announce_past

I added

CNT_announce_current


But, unless I uninstall/reinstall the module, loosing all content, the 
variables in conf/layout.php I've added don't get into the mod_layout 
table. I can see where in Boost it adds the content variables to the 
layout table but was wondering if there was an easy way of including 
that mechanisim in the module's update.php
