Hello golang-dev@googlegroups.com,

I'd like you to review this change to
https://code.google.com/p/go/

I think it will be helpful to include an example similar to these with the 
use of Funcs or Delims.

definition files would live near the source.
I don't think they necessarily would live near the source. In App Engine, yes,
but in other environments they'd live in some data directory known to the
program.

"Here we create a temporary directory and populate it with our sample template
definition files; usually the template files would already exist in some
location known to the program."

src/pkg/text/template/examplefiles_test.go:152: // Execute the template.
perhaps save the execution of the templates until the end, then just do them one
after the other. the lesson is clear without the repetition.

1. Clone the helpers.
