nixpkgs/pkgs/top-level/emscripten-packages.nix
Joachim Schiele c514693eb6 adds support to build emscripten packages using nix:
example usage:

- nix-env -I nixpkgs=../somewhere/nixpkgs -f default.nix -iA emscriptenPackages.libxml2
- nix-env -I nixpkgs=../somewhere/nixpkgs -f default.nix -iA emscriptenPackages.json_c
- nix-env -I nixpkgs=../somewhere/nixpkgs -f default.nix -iA emscriptenPackages.zlib
- nix-env -I nixpkgs=../somewhere/nixpkgs -f default.nix -iA emscriptenPackages.xmlmirror
