2011-08-06	* Refactoring: move parseExprFromFile() and parseExprFromString() into	Eelco Dolstra
	the EvalState class.
2010-04-13	* Use a symbol table to represent identifiers and attribute names	Eelco Dolstra
	efficiently. The symbol table ensures that there is only one copy of each symbol, thus allowing symbols to be compared efficiently using a pointer equality test.
2010-04-12	* Don't use ATerms for the abstract syntax trees anymore. Not	Eelco Dolstra
	finished yet.
2010-03-23	* Start of an evaluator that uses call-by-need (with thunk updating)	Eelco Dolstra
	instead of (memoised) call-by-name.
2006-09-04	* Use a proper namespace.	Eelco Dolstra
	* Optimise header file usage a bit. * Compile the parser as C++.
2004-02-04	* Use a map to lookup primops.	Eelco Dolstra
	* Various performance improvements in the evaluator. * Do not link against unused (and missing!) libraries (-lsglr, etc.).
2003-11-22	* Maintain integrity of the substitute and successor mappings when	Eelco Dolstra
	deleting a path in the store. * Allow absolute paths in Nix expressions. * Get nix-prefetch-url to work again. * Various other fixes.
2003-11-19	* Refactoring: put the Nix expression evaluator in its own library so	Eelco Dolstra
	that it can be used by multiple programs.
