-## Introduction
-
-The `.gyp` files in the NaCl source tree serve two purposes: they are used to
-build NaCl as part of Chromium (see ChromiumIntegration), and they can also be
-used to build NaCl standalone, as an alternative to the Scons build scripts.
-
-## Standalone Linux Gyp build
-
-In the top-level (`trunk/src`) directory: * `./native_client/build/gyp_nacl
-native_client/build/all.gyp -f make` * `make -j4`
-
-## Standalone Windows Gyp build
-
-In the top-level (`trunk/src`) directory: * If necessary: run `vcvarsall.bat`
-from the Visual Studio/VC directory. * `set GYP_MSVS_VERSION=2008` * `gclient
-runhooks` * `devenv native_client\build\all.sln /build Debug` It also works from
-the `native_client` directory: * `devenv build\all.sln /build Debug`
-
-## Tests
-
-Most of the NaCl tests cannot be run using the Gyp build, because the Gyp build
-does not know how to invoke the NaCl compiler. Gyp does not handle
-cross-compilation well in general. To run the NaCl tests you have to use the
-Scons build.
