Unspecified pieces

The TDS cannot address the following aspects of a functioning TeX system:

  1. The location of executable programs: this is too site-dependent even to recommend a location, let alone require one. A site may place executables outside the `texmf' tree altogether (e.g., `/usr/local/bin'), in a platform-dependent directory within `texmf', or elsewhere.
  2. Upgrading packages when new releases are made: we could find no way of introducing version specifiers into `texmf' that would do more good than harm, or that would be practical for even a plurality of installations.
  3. The location of implementation-specific files (e.g., TeX `.fmt' files): by their nature, these must be left to the implementor or TeX maintainer. See Section section Example implementation-specific trees.
  4. Precisely when a package or file should be considered "local", and where such local files are installed. See Section section Local additions for more discussion.
