# = MasterView - Rails-optimized (x)html friendly template engine 
# 
# MasterView is a ruby/rails optimized HTML/XHTML friendly template engine. 
# It is designed to use the full power and productivity of rails including 
# layouts, partials, and rails html helpers while still being editable/styleable 
# in a WYSIWYG HTML editor.

  # then the masterview files will again be checked (using modified time) to see if any files need to 
  # be re-parsed. In production mode ActionController::Base.perform_caching is normally true and thus
  # masterview files will only be parsed on first load. 
  # If this constant is set to false then no automatic watching or parsing occurs, it would be assumed
  # that the parsing would have been manually triggered prior.
