TODO LIST

Bugs, quirks, "features":
- Finish implementing clean URLs everywhere
- Accented filenames in local PDF files provoke a "403 Forbidden" error
- Authors with a "von" part have 0 paper when you click on their name, and the
  von part is not displayed (page author-details.php)
- Adding names with accents in BibTeX (Sylvain Hall{\'e}) does not really work
  (creates duplicate entries)

In the near future (easily implementable):
- Installation script
- Link to local PS or PDF using a "Browse" button instead of typing the URL in
  the form
- Conference page does not format paper entries in the same way as the
  others.
- Tighter check on proper format of category string
- After adding an author, provide a link to this new author
- Support deletion of papers and authors
- Support edition of authors
- Add a "tag" field to each paper, and export to bibtex file only marked items
- More complete search function
- Add other formats for displaying references
- Language is from a list of choices: make it an option instead of a free text 
  field
- Export/import whole database (via .bib file)
- In the comment field, include links to other papers in the database
  (pre-process the text field, recognize the link to the bibtex identifier,
  convert it to the proper dadrill HTML link and then send the text to markdown)
- Fancier error messages (better than using die)
- Add maintenance operations:
  - remove orphan authors
  - auto-add listed authors that are not in the author table
- Write documentation for installing and using
- Erds Numbers of authors

In the far future (will need more work):
- Automatic splitting of names:  support comma separated list of tokens
- Support for Bibtex style sheets
