Here's a current list of "component" names. Each ticket belongs to one of
them. The definitions are somewhat arbitrary and non-orthogonal, but represent what I (warner)
have been using to classify various issues.

First, the non-code things.

 * '''contrib''': problems with non-core things that live in the
   source:contrib/ directory, like the various FUSE implementations.
 * '''dev-infrastructure''': things that help us build Tahoe, like the
   buildbot, the automated speed/memory/code-coverage tests (and the web
   pages which display their results), the IRC channels and mailing lists,
   and this Trac bugtracker itself.
 * '''operational''': things involved in running a Tahoe grid, external tools
   used to monitor or maintain a grid, tools used to launch a tahoe node,
   issues with te allmydata.com grid.
 * '''website''': things about the allmydata.org website and its Trac
   instance
 * '''unknown''': not yet categorized. All tickets default to this component
   until someone updates it.

Now, the tickets that can be resolved by changing something in the Tahoe
source code tree:

 * '''code''': catch-all for anything that isn't classified better. Having a
   lot of tickets here suggests that maybe we need to add a component or two.
  * '''code-dirnodes''': anything involving tahoe directories
  * '''code-encoding''': immutable-file encoding format/layout, cap format,
    encoding/decoding algorithms
  * frontend stuff
   * '''code-frontend''': general frontend things: new user-facing
     interfaces, FTP/SFTP servers, FUSE-like interfaces
   * '''code-frontend-cli''': CLI tools
   * '''code-frontend-w32''': windows frontend stuff
   * '''code-frontend-web''': webapi interfaces, user-facing "WUI" interfaces
  * '''code-mutable''': anything involving mutable files: encoding/decoding,
    share format
  * '''code-network''': introducer, locating storage servers,
    establishing/maintaining connections to them
  * '''code-nodeadmin''': node startup/shutdown, tools to create nodes,
    logging tools, management/monitoring tools, manhole, disk-space-limiting
    tools
  * '''code-peerselection''': server selection/sorting algorithm, rebalancing
    code, allocation policy, swarming-download
  * '''code-storage''': storage server implementation, share-storage
    directory layout, client-to-server share transfer protocol
  * '''documentation''': (deprecated, use docs keyword)
  * '''packaging''': setup.py script, library dependencies, creation of
    binary packages (deb/rpm/exe), licensing, installation instructions
