I've been using Template Toolkit (Perl) for many years and need 
something similar in Ruby to process static html files. In Template 
Toolkit I have a config file and a go.sh one-liner (see below) with 
which I can recursively process a directory of templates to update a 
whole site using `./go.sh -a`. What's the closest to this in the Ruby 
templating ecosystem? Erubis didn't appear to have what I want.

gvim

$ ttree.cfg

src  = /var/www/html/mysite/dev/tt/src
lib  = /var/www/html/mysite/dev/tt/lib
dest = /var/www/html/mysite/dev/pub

ignore = ^#
ignore = ~$
ignore = .sh$
ignore = .swp$

define rootdir = /var/www/html/mysite/dev/
# define rooturl =
define debug = 0

suffix sht=html
suffix sph=php
