Announcement text: ---------------------------------------------------------------------- You can hyperling DOI numbers to dx.doi.org. Some publishers have elected to use some nasty characters in their doi numbering scheme (<, >, ; have all been spotted). This will either upset (La)TeX, or your pdf reader. This style file contains a single user-level command doi{}, which takes a doi number, and creates a hyperlink from it. ----------------------------------------------------------------------
