+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
+ 5. Multiple Implementations
+ 6. Minimize Memory Allocation
+ 7. No Virtual Methods

+llvm/lib/Support/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.
