# 1. LEVEL - Must be set as per normal semantics: The depth from the top of tree
|

# 2. LIBNAME - Name of library to link together. Forms lib<LIBNAME>.bc
|
|
# 3. EXPORTED_SYMBOL_LIST - If this symbol is defined, it contains a comma
|
|
# separated list of symbols that are exported by the library. All other
|
|
# symbols are marked internal, reducing namespace pollution.
