 Introduction
 ------------
 
 libbcc is an LLVM bitcode execution engine which compiles the bitcode
-to an in-memory executable.  It comes with a *just-in-time bitcode
-compiler*, which translates the bitcode to machine code, and a *caching
+to an in-memory executable.  libbcc provides a *just-in-time bitcode
+compiler*, which translates the bitcode into machine code, and a *caching
 mechanism*, which saves the in-memory executable after the compilation.
 Here are some highlights of libbcc:

+A cache file (denoted as \*.oBCC) for libbcc consists of several sections:
 header, string pool, dependencies table, relocation table, exported
 variable list, exported function list, pragma list, function information
 table, and bcc context.  Every section should be aligned to a word size.
