/**
* Horde Template Admin
*
* $Horde: horde/admin/templates.php,v 1.15.10.1 2005/01/03 12:25:29 jan Exp $
*
* First stab at a template loader for horde, to be used by the horde
* admin to load alternate individual templates or entire themes for the
* Horde_Template system.
* - gives a list of active horde apps and their /templates directory
* contents to choose from
* - user can drill down to a specific file and load as many alternate
* templates as required
* - it allows saving of templates only on actual files (and not
* directories) and does not show hidden files.
* - the alternate templates are stored in the VFS under the directory
* path:
* .horde_templates/$app/sometemplatedir/templatefile
* so that directory would contain all the alternatives for that
* template.
* - TODO: don't show certain other files, like CVS directories; comments;
* theme selection and storing in the VFS under:
* .horde_templates/$app/_themes/$theme/sometemplatedir/templatefile
* to be able to call up an entire theme group of templates? better error
* checking; downloading of original templates; the application side of
* allowing a different template to be chosen/prefs/etc.
