-Design Of lib/System
-====================
-
-The software in this directory is designed to completely shield LLVM from any
-and all operating system specific functionality. It is not intended to be a
-complete operating system wrapper (such as ACE), but only to provide the
-functionality necessary to support LLVM.
-
-The software located here, of necessity, has very specific and stringent design
-rules. Violation of these rules means that cracks in the shield could form and
-the primary goal of the library is defeated. By consistently using this library,
-LLVM becomes more easily ported to new platforms since the only thing requiring 
-porting is this library.
-
-Complete documentation for the library can be found in the file:
-  llvm/docs/SystemLibrary.html 
-or at this URL:
-  http://llvm.org/docs/SystemLibrary.html
-
-While we recommend that you read the more detailed documentation, for the 
-impatient, here's a high level summary of the library's requirements.
-
- 1. No system header files are to be exposed through the interface.
- 2. Std C++ and Std C header files are okay to be exposed through the interface.
- 3. No exposed system-specific functions.
- 4. No exposed system-specific data.
- 5. Data in lib/System classes must use only simple C++ intrinsic types.
- 6. Errors are handled by returning "true" and setting an optional std::string
- 7. Library must not throw any exceptions, period.
- 8. Interface functions must not have throw() specifications.
- 9. No duplicate function impementations are permitted within an operating
-    system class.
-
-To accomplish these requirements, the library has numerous design criteria that 
-must be satisfied. Here's a high level summary of the library's design criteria:
-
- 1. No unused functionality (only what LLVM needs)
- 2. High-Level Interfaces
- 3. Use Opaque Classes
- 4. Common Implementations</a></li>
- 5. Multiple Implementations</a></li>
- 6. Minimize Memory Allocation</a></li>
- 7. No Virtual Methods

-llvm/lib/System/Unix README
-===========================
-
-This directory provides implementations of the lib/System classes that
-are common to two or more variants of UNIX. For example, the directory 
-structure underneath this directory could look like this:
-
-Unix           - only code that is truly generic to all UNIX platforms
-  Posix        - code that is specific to Posix variants of UNIX
-  SUS          - code that is specific to the Single Unix Specification 
-  SysV         - code that is specific to System V variants of UNIX
-
-As a rule, only those directories actually needing to be created should be
-created. Also, further subdirectories could be created to reflect versions of
-the various standards. For example, under SUS there could be v1, v2, and v3
-subdirectories to reflect the three major versions of SUS.
