BibTeX's output line breaking mechanism has been implemented. The BST-to-Lisp compiler now deals with WHILE$ loops with complicated data flow, makes some variables constant, and tries to deal with slightly broken style files. Some bugs in the compiler and in the run-time have been fixed. A new test suite shows that most BibTeX styles on CTAN can now be correctly compiled to Lisp.
The compiler now supports BibTeX macros (named strings). It makes some variables lexical (rather than special), leading to more readable Lisp code. It is also more careful with respect to the Common Lisp package system. The interpreter and the compiler now handle empty BST function blocks. A capitalization bug has been fixed.
