-# Deno Prototype 2
-
-## Status
-
-This code is a rewrite of the privileged parts of Deno. It will soon become
-the root of the project.
-
-There are several goals:
-
-* Use the gn build system for fast builds, sane configuration, and easy
-  linking into Chrome.
-
-* Use V8 snapshots to improve startup time.
-
-* Remove Golang. Although it has been working nicely, I am concerned the
-  double GC will become a problem sometime down the road.
-
-* Distribute a C++ library called libdeno, containing the snapshotted
-  typescript runtime.
-
-* Test the message passing and other functionality at that layer before
-  involving higher level languages.
-
-The contenders for building the privileged part of Deno are Rust and C++.
-Thanks to Chrome and gn, using C++ to link into high level libraries is not
-untenable. However, there's a lot of interest in Rust in the JS community and
-it seems like a reasonable choice. TBD.
-
-There are many people exploring the project, so care will be taken to keep the
-original code functional while this is developed. However, once it's ready
-the code in this deno2/ directory will be moved to the root.
-
-
-## Prerequisites
-
-Get Depot Tools and make sure it's in your path.
-http://commondatastorage.googleapis.com/chrome-infra-docs/flat/depot_tools/docs/html/depot_tools_tutorial.html#_setting_up
-
-For linux you need these prereqs:
-
-    sudo apt-get install libgtk-3-dev pkg-config ccache
-
-
-## Build
-
-First install the javascript deps.
-
-    cd js; yarn install
-
-TODO(ry) Remove the above step by a deps submodule.
-
-Wrapper around the gclient/gn/ninja for end users. Try this first:
-
-    ./tools/build.py --use_ccache --debug
-
-If that doesn't work, or you need more control, try calling gn manually:
-
-    gn gen out/Debug --args='cc_wrapper="ccache" is_debug=true '
-
-Then build with ninja:
-
-    ninja -C out/Debug/ deno
-
-
-Other useful commands:
-
-    gn args out/Debug/ --list # List build args
-    gn args out/Debug/ # Modify args in $EDITOR
