+/* Objdump overview.
+
+ Objdump displays information about one or more object files, either on
+ their own, or inside libraries. It is commonly used as a disassembler,
+ but it can also display information about file headers, symbol tables,
+ relocations, debugging directives and more.
+
+ The flow of execution is as follows:
+
+ 1. Command line arguments are checked for control switches and the
+ information to be displayed is selected.
+
+ 2. Any remaining arguments are assumed to be object files, and they are
+ processed in order by display_bfd(). If the file is an archive each
+ of its elements is processed in turn.
+
+ 3. The file's target architecture and binary file format are determnined
+ by bfd_check_format(). If they are recognised, then dump_bfd() is
+ called.
+
+ 4. dump_bfd() in turn calls seperate functions to display the requested
+ item(s) of infomation(s). For example dissasemble_data() is called if
+ a disassmebly has been requested.
+
+ When disassembling the code loops through blocks of instructions bounded
+ by symbols, calling dissassemble_bytes() on each block. The actual
+ disassembling is done by the libopcodes library, via a function pointer
+ supplied by the disassembler() function. */
