-// A class for indicating whether an assertion was successful.  When
-// the assertion wasn't successful, the AssertionResult object
-// remembers a non-empty message that describes how it failed.
-//
-// To create an instance of this class, use one of the factory functions
-// (AssertionSuccess() and AssertionFailure()).
-//
-// This class is useful for two purposes:
-//   1. Defining predicate functions to be used with Boolean test assertions
-//      EXPECT_TRUE/EXPECT_FALSE and their ASSERT_ counterparts
-//   2. Defining predicate-format functions to be
-//      used with predicate assertions (ASSERT_PRED_FORMAT*, etc).
-//
-// For example, if you define IsEven predicate:
-//
-//   testing::AssertionResult IsEven(int n) {
-//     if ((n % 2) == 0)
-//       return testing::AssertionSuccess();
-//     else
-//       return testing::AssertionFailure() << n << " is odd";
-//   }
-//
-// Then the failed expectation EXPECT_TRUE(IsEven(Fib(5)))
-// will print the message
-//
-//   Value of: IsEven(Fib(5))
-//     Actual: false (5 is odd)
-//   Expected: true
-//
-// instead of a more opaque
-//
-//   Value of: IsEven(Fib(5))
-//     Actual: false
-//   Expected: true
-//
-// in case IsEven is a simple Boolean predicate.
-//
-// If you expect your predicate to be reused and want to support informative
-// messages in EXPECT_FALSE and ASSERT_FALSE (negative assertions show up
-// about half as often as positive ones in our tests), supply messages for
-// both success and failure cases:
-//
-//   testing::AssertionResult IsEven(int n) {
-//     if ((n % 2) == 0)
-//       return testing::AssertionSuccess() << n << " is even";
-//     else
-//       return testing::AssertionFailure() << n << " is odd";
-//   }
-//
-// Then a statement EXPECT_FALSE(IsEven(Fib(6))) will print
-//
-//   Value of: IsEven(Fib(6))
-//     Actual: true (8 is even)
-//   Expected: false
-//
-// NB: Predicates that support negative Boolean assertions have reduced
-// performance in positive ones so be careful not to use them in tests
-// that have lots (tens of thousands) of positive Boolean assertions.
-//
-// To use this class with EXPECT_PRED_FORMAT assertions such as:
-//
-//   // Verifies that Foo() returns an even number.
-//   EXPECT_PRED_FORMAT1(IsEven, Foo());
-//
-// you need to define:
-//
-//   testing::AssertionResult IsEven(const char* expr, int n) {
-//     if ((n % 2) == 0)
-//       return testing::AssertionSuccess();
-//     else
-//       return testing::AssertionFailure()
-//         << "Expected: " << expr << " is even\n  Actual: it's " << n;
-//   }
-//
-// If Foo() returns 5, you will see the following message:
-//
-//   Expected: Foo() is even
-//     Actual: it's 5

-Fuses Google Test source code into a .h file and a .cc file.
-
-SYNOPSIS
-       fuse_gtest_files.py [GTEST_ROOT_DIR] OUTPUT_DIR
-
-       Scans GTEST_ROOT_DIR for Google Test source code, and generates
-       two files: OUTPUT_DIR/gtest/gtest.h and OUTPUT_DIR/gtest/gtest-all.cc.
-       Then you can build your tests by adding OUTPUT_DIR to the include
-       search path and linking with OUTPUT_DIR/gtest/gtest-all.cc.  These
-       two files contain everything you need to use Google Test.  Hence
-       you can "install" Google Test by copying them to wherever you want.
-
-       GTEST_ROOT_DIR can be omitted and defaults to the parent
-       directory of the directory holding this script.
-
-EXAMPLES
-       ./fuse_gtest_files.py fused_gtest
-       ./fuse_gtest_files.py path/to/unpacked/gtest fused_gtest
-
-This tool is experimental.  In particular, it assumes that there is no
-conditional inclusion of Google Test headers.  Please report any
-problems to googletestframework@googlegroups.com.  You can read

-The `gtest-config' script provides access to the necessary compile and linking
-flags to connect with Google C++ Testing Framework, both in a build prior to
-installation, and on the system proper after installation. The installation
-overrides may be issued in combination with any other queries, but will only
-affect installation queries if called on a built but not installed gtest. The
-installation queries may not be issued with any other types of queries, and
-only one installation query may be made at a time. The version queries and
-compiler flag queries may be combined as desired but not mixed. Different
-version queries are always combined with logical "and" semantics, and only the
-last of any particular query is used while all previous ones ignored. All
-versions must be specified as a sequence of numbers separated by periods.
-Compiler flag queries output the union of the sets of flags when combined.
-
- Examples:
-  gtest-config --min-version=1.0 || echo "Insufficient Google Test version."
-
-  g++ $(gtest-config --cppflags --cxxflags) -o foo.o -c foo.cpp
-  g++ $(gtest-config --ldflags --libs) -o foo foo.o

-"""Script for branching Google Test/Mock wiki pages for a new version.
-
-SYNOPSIS
-       release_docs.py NEW_RELEASE_VERSION
-
-       Google Test and Google Mock's external user documentation is in
-       interlinked wiki files.  When we release a new version of
-       Google Test or Google Mock, we need to branch the wiki files
-       such that users of a specific version of Google Test/Mock can
-       look up documentation relevant for that version.  This script
-       automates that process by:
-
-         - branching the current wiki pages (which document the
-           behavior of the SVN trunk head) to pages for the specified
-           version (e.g. branching FAQ.wiki to V2_6_FAQ.wiki when
-           NEW_RELEASE_VERSION is 2.6);
-         - updating the links in the branched files to point to the branched
-           version (e.g. a link in V2_6_FAQ.wiki that pointed to
-           Primer.wiki#Anchor will now point to V2_6_Primer.wiki#Anchor).
-
-       NOTE: NEW_RELEASE_VERSION must be a NEW version number for
-       which the wiki pages don't yet exist; otherwise you'll get SVN
-       errors like "svn: Path 'V1_7_PumpManual.wiki' is not a
-       directory" when running the script.
-
-EXAMPLE
-       $ cd PATH/TO/GTEST_SVN_WORKSPACE/trunk
-       $ scripts/release_docs.py 2.6  # create wiki pages for v2.6
-       $ svn status                   # verify the file list
-       $ svn diff                     # verify the file contents
-       $ svn commit -m "release wiki pages for v2.6"
