I've added the ability to a local copy of HTML::Template to allow
HTML_TEMPLATE_ROOT to contain a ":" separated list of paths. This is
useful for our setup becuase we have a number of applications that are
basically subclasses of other applications and we would like to share
templates with the base application, yet make it easy to overload some
templates.
How it works i I can configure the appliction with:
SetEnv HTML_TEMPLATE_ROOT /dir/app1/templates:/dir/app2/templates
ANd when accessing this app, HTML::Template first looks in
/dir/app1/templates for the file in question. If the file is not found,
then it will look in /dir/app2/templates and so on. This is similar to
the "path" parameter to HTML::Template->new(), except it works at the
configuration level.
The patch that provides this funcionality is quite simple:
--- Template.pm 2001/09/06 21:29:58 1.1.1.4
+++ Template.pm 2001/09/06 21:32:11 1.4

Anyway, in case this is useful to the community I thought I would send
it along :).
