- Make sure your node workspace is clean (clean `git status`) should be sufficient.

- Configure Node with the specific [ICU version](http://icu-project.org/download) you want to upgrade to, for example:

./configure \

--with-intl=small-icu \

--with-icu-source=http://download.icu-project.org/files/icu4c/56.1/icu4c-56_1-src.zip

- Verify the node build works

make test-ci

- Now, copy `deps/icu` over to `deps/icu-small`

python tools/icu/shrink-icu-src.py

- Now, do a clean rebuild of node to test:

(TODO: fix this when these options become default)

./configure --with-intl=small-icu --with-icu-source=deps/icu-small

make

the `configure_intl()` function. It should match the ICU URL used in the

first step. When this is done, the following should build with full ICU.

rm -rf out deps/icu deps/icu4c*

./configure --with-intl=full-icu --download=all

The files in this directory were written for the node.js effort. It's

the intent of their author (Steven R. Loomis / srl295) to merge them
