In Nixpkgs, the attribute in all-packages.nix corresponding to a
package is usually equal to the package name. However, this doesn't
work if the package contains a dash, which is fairly common. The
convention is to replace the dash with an underscore (e.g. "dbus-lib"
becomes "dbus_glib"), but that's annoying. So now dashes are valid in
variable / attribute names, allowing you to write:
dbus-glib = callPackage ../development/libraries/dbus-glib { };
and
buildInputs = [ dbus-glib ];
Since we don't have a negation or subtraction operation in Nix, this
is unambiguous.

The Nix Emacs mode supports syntax highlighting, somewhat sensible indenting, and refilling of comments. To enable Nix mode in Emacs, add something like this to your ~/.emacs file: (load "/nix/share/emacs/site-lisp/nix-mode.el") This automatically causes Nix mode to be activated for all files with extension `.nix'.
