Filter support?

[amit777]

Hi, I was wondering if this module support filter definitions. If so, would you be able to direct me to an example of how to define one?

For example

[% foo | upper %]   

This would output foo in uppercase

I can't remember (it's been years!) but maybe https://www.github.com/ashb/template/tree/master/t%2Ffilter.js
