It has a minor bug in its build system that needs to fixed. 06 Dec 2002; Rodney Rees : changed sparc ~sparc keywords *stratego-0.8.1 (20 Oct 2002) 20 Oct 2002; Karl Trygve Kalleberg stratego-0.8.1.ebuild files/digest-stratego-0.8.1 : New upstream version. 02 Nov 2002; Karl Trygve Kalleberg stratego-0.8.1.ebuild : Fixed sandbox violation. *stratego-0.8 (20 Oct 2002) 02 Nov 2002; Karl Trygve Kalleberg stratego-0.8.ebuild : Fixed sandbox violation. 20 Oct 2002; Karl Trygve Kalleberg stratego-0.8.ebuild files/digest-stratego-0.8 : New upstream version. *stratego-0.7 (11 Apr 2002) 02 Nov 2002; Karl Trygve Kalleberg stratego-0.7.ebuild files/digest-stratego-0.7 : This version violates the sandbox and is superceded by 0.8, so I'm removing it. 11 Apr 2002; Karl Trygve Kalleberg stratego-0.7.ebuild files/digest-stratego-0.7: Stratego is a modular language for the specification of fully automatic program transformation systems based on the paradigm of RewritingStrategies. In Stratego, basic transformation rules are expressed by means of labeled conditional rewrite rules. Exhaustively applying all rewrite rules in a collection of valid rules is often not desirable; a system of rules can be non-terminating, or, more frequently, non-confluent. The latter means that different outcomes of the normalization process are possible depending on the position of application and the selection of rules. Therefore, it is necessary to have more control over the application of rules. In standard systems based on rewriting, normalization is controlled by a fixed default RewritingStrategy. In such systems more control is achieved by encoding the desired strategy with additional rewrite rules that spell out a traversal over the abstract syntax tree and apply the transformations in the desired order.
