Eelco Dolstra 777e13b94b * Nix now has three different formats for the log information it
writes to stderr:
  
  - `pretty': the old nested style (default)
  - `escapes': uses escape codes to indicate nesting and message
    level; can be processed using `log2xml'
  - `flat': just plain text, no nesting

  These can be set using `--log-type TYPE' or the NIX_LOG_TYPE
  environment variable.

argument is specified.

Eelco Dolstra 447089a5f6 * Catch SIGINT to terminate cleanly when the user tries to interrupt
Nix.  This is to prevent Berkeley DB from becoming wedged.

  Unfortunately it is not possible to throw C++ exceptions from a
  signal handler.  In fact, you can't do much of anything except
  change variables of type `volatile sig_atomic_t'.  So we set an
  interrupt flag in the signal handler and check it at various
  strategic locations in the code (by calling checkInterrupt()).
  Since this is unlikely to cover all cases (e.g., (semi-)infinite
  loops), sometimes SIGTERM may now be required to kill Nix.

Eelco Dolstra 4a373a3e9a * Implemented Eelco V.'s `nix-env -I' command to specify the default
path of the Nix expression to be used with the import, upgrade, and
  query commands.  For instance,

  $ nix-env -I ~/nixpkgs/pkgs/system/i686-linux.nix

  $ nix-env --query --available   [aka -qa]
  sylpheed-0.9.7
  bison-1.875
  pango-1.2.5
  subversion-0.35.1
  ...

  $ nix-env -i sylpheed

  $ nix-env -u subversion

  There can be only one default at a time.

* If the path to a Nix expression is a symlink, follow the symlink
  prior to resolving relative path references in the expression.
