-// The next three tests will only run automatically with Chrome branded builds
-// because they require the PDF preview plug-in. To run these tests manually for
-// Chromium (non-Chrome branded) builds in a development environment:
-//
-//   1) Remove "MAYBE_" in the first line of each test definition
-//   2) Build Chromium browser_tests
-//   3) Make a copy of the PDF plug-in from a recent version of Chrome (Canary
-//      or a recent development build) to your Chromium build:
-//      - On Linux and Chrome OS, copy /opt/google/chrome/libpdf.so to
-//        <path-to-your-src>/out/Debug
-//      - On OS X, copy PDF.plugin from
-//        <recent-chrome-app-folder>/*/*/*/*/"Internet Plug-Ins" to
-//        <path-to-your-src>/out/Debug/Chromium.app/*/*/*/*/"Internet Plug-Ins"
-//   4) Run browser_tests with the --enable-print-preview flag
