# Given a single argument, being the folder to a local copy of the npm package to "install"
# copy it to the local node_modules folder, then make sure it has no node_modules of its own.
# This way you can npm install locally afterwards to cover remaining dependencies and
# everything will work right.
function npm_import {
  export pkgname=`basename $1`
  export pkgdir="node_modules/$pkgname"
  if [ -d "$pkgdir" ]; then
    rm -rf "$pkgdir"
