The webapp is a web server that displays a shiny interface.

## other features

* there could be a UI to export a file, which would make it be served up
  over http by the web app
* there could be a UI (some javascript thing) in the web browser to
  submit urls to the web app to be added to the annex and downloaded.
  See: [[todo/wishlist:_an_"assistant"_for_web-browsing_--_tracking_the_sources_of_the_downloads]]
* Display the `inotify max_user_watches` exceeded message. **done**
* Display something sane when kqueue runs out of file descriptors.
* allow removing git remotes **done**
* allow disabling syncing to here, which should temporarily disable all
  local syncing. **done**

## first start **done**

* make git repo **done**
* generate a nice description like "joey@hostname Desktop/annex" **done**
* record repository that was made, and use it next time run **done**
* write a pid file, to prevent more than one first-start process running
  at once **done**

## security **acceptable/done**

* Listen only to localhost. **done**
* Instruct the user's web browser to open an url that contains a secret
  token. This guards against other users on the same system. **done**
  (I would like to avoid passwords or other authentication methods,
  it's your local system.)
* Don't pass the url with secret token directly to the web browser,
  as that exposes it to `ps`. Instead, write a html file only the user can read,
  that redirects to the webapp. **done**
* Alternative for Linux at least would be to write a small program using
  GTK+ Webkit, that runs the webapp, and can know what user ran it, avoiding
  needing authentication.
