+/******************************************************************************
+
+This is the layer that the architecture module uses to access disassemble
+functionality.
+
+Currently, it wraps capstone, but that could change in the future. It exists
+precisely to make swapping out disassemblers easy, because disassembler details
+(like capstone types) will not be intertwined in the architecture plugin code.
+
+Also, with the disassembler object separate, we can link it against
+easy-to-compile test harnesses like the speed test.
+
+There are three main functions:
+
+powerpc_init() - initializes this module
+powerpc_release() - un-initializes this module
+powerpc_decompose() - converts bytes into decomp_result
+powerpc_disassemble() - converts decomp_result to string
+
+Then some helpers if you need them:
+
