METHODS

Constructor. No arguments are required/supported.

expand_variables

This is the method which is called by the Templer::Plugin::Factory to expand the variables contained in a Templer::Site::Page object.

Variables are written in the file in the form "key: value", and are internally stored within the Page object as a hash.

This method iterates over each key & value and updates any that seem to refer to shell commands.
