Displays all types of executable files, and also object ".o" files as
generated by (other) compilers/assemblers.  will show you the (very simple)
structure of executables generated by EC, but also supports complex
overlay-files.  also dumps labels (like XREF's and XDEF's).

most important of all, ShowHunk features a disassembler for
code-hunks. use the option 'DISASM/S'
