I usually try to run the program first, because if it is available in
the channel nix will print the package name:

$ xsltproc
The program ‘xsltproc’ is currently not installed. You can install it by typing:
  nix-env -i libxslt

But some packages aren't available in the channel (if their
expressions lack meta.platforms). So if the above fails I do what
Mathijs says and grep for it in the nixpkgs tree.
