* npm_binary (download tarball packaged npm apps)
* bower_archive (download a zip file, to be put in WORKSPACE)
* bower_component (defining a bower library, with dependency )
* bower_component_bundle (zipping up libraries together)
* js_component (insert plain js file into bower component bundle)
* bower2bazel.py: run bower to find dependencies, generate a .bzl to
define archives and define components
Tested:
python tools/js/bower2bazel.py -w lib/js/bower_archives.bzl -b \
lib/js/bower_components.bzl
bazel build polygerrit-ui:components
unzip -v bazel-bin/polygerrit-ui/components.zip > /tmp/baz
buck build polygerrit-ui:polygerrit_components
unzip -v buck-out/gen/polygerrit-ui/polygerrit_components/polygerrit_components.bower_components.zip > /tmp/buck
diff /tmp/buck /tmp/baz
The diff corresponds to newer file versions pinned through bower2bazel.

"""Hash the contents of a bower component directory.

|
|
This is a stable hash of a directory downloaded with `bower install`, minus

the .bower.json file, which is autogenerated each time by bower. Used in lieu
|
|
of hashing a zipfile of the contents, since zipfiles are difficult to hash in

a stable manner.
