+      KLEE is a symbolic virtual machine built on top of the LLVM compiler
+      infrastructure. Currently, there are two primary components:
+
+      1. The core symbolic virtual machine engine; this is responsible for
+         executing LLVM bitcode modules with support for symbolic values. This
+         is comprised of the code in lib/.
+
+      2. A POSIX/Linux emulation layer oriented towards supporting uClibc, with
+         additional support for making parts of the operating system environment
+         symbolic.
+
+      Additionally, there is a simple library for replaying computed inputs on
+      native code (for closed programs). There is also a more complicated
+      infrastructure for replaying the inputs generated for the POSIX/Linux
+      emulation layer, which handles running native programs in an environment
+      that matches a computed test input, including setting up files, pipes,
+      environment variables, and passing command line arguments.
