Class SpecialAttrWrapper

This is a wrapper for what we call a 'Node special attribute.' This is any of the attributes of a Node that we can reference from Environment variable substitution, such as $TARGET.abspath or $SOURCES[1].filebase. We implement the same methods as Literal so we can handle special characters, plus a for_signature method, such that we can return some canonical string during signature calculation to avoid unnecessary rebuilds.

Method Summary
	`__init__(self, lstr, for_signature)` The for_signature parameter, if supplied, will be the canonical string we return from for_signature().
	`__str__(self)`
	`escape(self, escape_func)`
	`for_signature(self)`
	`is_literal(self)`

Method Details

init(self, lstr, for_signature=None)
(Constructor)

The for_signature parameter, if supplied, will be the canonical string we return from for_signature(). Else we will simply return lstr.
