texlive-doi 49435 Create correct hyperlinks for DOI numbers

You can hyperlink DOI numbers to doi.org. However, some publishers have elected to use nasty characters in their DOI numbering scheme (<, >, _ and ; have all been spotted). This will either upset LaTeX, or your PDF reader. This package contains a single user-level command \doi, which takes a DOI number, and creates a correct hyperlink to the target of the DOI.
