The document files should preferrably reside within the same directory as the abstract page (and thus, in the same directory with all the document files of the given volume resp. issue).
Note: The naming of the document files is not specified. Possible
schemes are:
- last names of authors, e.g.: hermix.dvi. hermix.ps, hermix.pdf
- volume, issue, document number information: 5_1_1.dvi, 5_1_1.ps,
5_1_1.pdf
