Less good file formats.

  1. multi-line records (para vs fixed number etc.)
  2. Multi-type ascii records.
  3. DBM (not standard/often limits on length/requires serialization for complex results).
  4. Things which really require a lexer and parser.
  5. MARC/PDF- At least well documented. Local processing possible.
  6. XBASE-Modules for its use. Local processing possible.
  7. Image file formats (ppm is best style of a bad bunch. Vector ones look best as pdf-style.)
  8. Serious compression (text compression with imbedded state machines).
  9. Perl- very flexible, trivial to use, but language-specific.
