oom_dump extracts useful information from Google Chrome OOM  minidumps.

To build one needs a google-breakpad checkout
(http://code.google.com/p/google-breakpad/).

First, one needs to build and install breakpad itself. For instructions
check google-breakpad, but currently it's as easy as:

  ./configure
  make
  sudo make install

(the catch: breakpad installs .so into /usr/local/lib, so you might
need some additional tweaking to make it discoverable, for example,
put a soft link into /usr/lib directory).

Next step is to build v8.  Note: you should build x64 version of v8,
if you're on 64-bit platform, otherwise you would get link error when
building oom_dump.

The last step is to build oom_dump itself.  The following command should work:

  cd <v8 working copy>/tools/oom_dump
  scons BREAKPAD_DIR=<path to google-breakpad working copy>

(Additionally you can control v8 working copy dir, but default---../..---
should work just fine).

If everything goes fine, oom_dump <path to minidump> should print
some useful information about OOM crash.
