+# C++ support for RT-Thread #
+
+This is the C++ component in RT-Thread RTOS. In order to support C++ language, this component
+implement a basic environment, such as new/delete operators.
+
+Because RT-Thread RTOS is used in embedded system mostly, there are some rules for C++ applications:
+1. DOES NOT use exception.
+2. DOES NOT use Run-Time Type Information (RTTI).
+3. Template is discouraged and it easily causes code text large.
+4. Static class variables are discouraged. The time and place to call their constructor function could not be precisely controlled and make multi-threaded programming a nightmare.
+5. Multiple inheritance is strongly discouraged, as it can cause intolerable confusion.
+
+*NOTE*: For armcc compiler, the libc must be enable.
