-# Customization Points
-
-The custom directory is an injection point for custom user configurations.
-
-## Header `gtest.h`
-
-### The following macros can be defined:
-
-*   `GTEST_OS_STACK_TRACE_GETTER_` - The name of an implementation of
-    `OsStackTraceGetterInterface`.
-*   `GTEST_CUSTOM_TEMPDIR_FUNCTION_` - An override for `testing::TempDir()`. See
-    `testing::TempDir` for semantics and signature.
-
-## Header `gtest-port.h`
-
-The following macros can be defined:
-
-### Logging:
-
-*   `GTEST_LOG_(severity)`
-*   `GTEST_CHECK_(condition)`
-*   Functions `LogToStderr()` and `FlushInfoLog()` have to be provided too.
-
-### Threading:
-
-*   `GTEST_HAS_NOTIFICATION_` - Enabled if Notification is already provided.
-*   `GTEST_HAS_MUTEX_AND_THREAD_LOCAL_` - Enabled if `Mutex` and `ThreadLocal`
-    are already provided. Must also provide `GTEST_DECLARE_STATIC_MUTEX_(mutex)`
-    and `GTEST_DEFINE_STATIC_MUTEX_(mutex)`
-*   `GTEST_EXCLUSIVE_LOCK_REQUIRED_(locks)`
-*   `GTEST_LOCK_EXCLUDED_(locks)`
-
-### Underlying library support features
-
-*   `GTEST_HAS_CXXABI_H_`
-
-### Exporting API symbols:
-
-*   `GTEST_API_` - Specifier for exported symbols.
-
-## Header `gtest-printers.h`
-
-*   See documentation at `gtest/gtest-printers.h` for details on how to define a
-    custom printer.
