Erubis is a fast, secure, and very extensible implementation of eRuby.
It has the following features:
* Very fast, almost three times faster than ERB and about ten percent
 faster than eruby (implemented in C).
* File caching of converted Ruby script support.
* Auto escaping (sanitizing) support, it means that '<%= %>' can be
 escaped in default. It is desirable for web application.
* Spaces around '<% %>' are trimmed automatically only when '<%' is at the
 beginning of line and '%>' is at the end of line.
* Embedded pattern changeable (default '<% %>'), for example '[% %]' or
 '<? ?>' are available.
* Enable to handle Processing Instructions (PI) as embedded pattern (ex.
 '<?rb ... ?>'). This is desirable for XML/HTML than '<% .. %>' because
 the latter breaks HTML design but the former doesn't.
* Multi-language support (Ruby/PHP/C/Java/Scheme/Perl/Javascript).
* Context object available and easy to combine eRuby template with YAML
 datafile (see the below example).
* Print statement available.
* Easy to expand and customize in subclass
* Ruby on Rails support.
* Mod_ruby support.
