+This module serves the purpose of generating debug symbols. We use LLVM's
 [source level debugging](http://llvm.org/docs/SourceLevelDebugging.html) features for generating
 the debug information. The general principle is this:

 such as datatype layout, function signatures, block layout, variable location and scope information,
 etc. It is the purpose of this module to generate correct metadata and insert it into the LLVM IR.
 
 As the exact format of metadata trees may change between different LLVM versions, we now use LLVM
 [DIBuilder](http://llvm.org/docs/doxygen/html/classllvm_1_1DIBuilder.html) to create metadata

+The public API of the module is a set of functions that will insert the correct metadata into the
 LLVM IR when called with the right parameters. The module is thus driven from an outside client with
 functions like `debuginfo::create_local_var(bcx: block, local: @ast::local)`.
