What would be the best way for me to customize custom sample data during installation of Joomla? In my particular case, I would like to replace certain words (or tokens, like %NAME%, %CITY%, etc.) within articles and the stored content of various types of modules (Custom HTML, Widgetkit 1.x).
If not during installation, then would having something that would be replaced on-the-fly (i.e. {myreplacecomponent name}, {myreplacecomponent city}) be more viable?
