+/* The difference between readelf and objdump:
+ Both programs are capabale of displaying the contents of ELF format files,
+ so why does the binutils project have two file dumpers ?
+
+ The reason is that objdump sees an ELF file through a BFD filter of the
+ world; if BFD has a bug where, say, it disagrees about a machine constant
+ in e_flags, then the odds are good that it will remain internally
+ consistent. The linker sees it the BFD way, objdump sees it the BFD way,
+ GAS sees it the BFD way. There was need for a tool to go find out what
+ the file actually says.
+
+ This is why the readelf program does not link against the BFD library - it
+ exists as an independent program to help verify the correct working of BFD.
+
+ There is also the case that readelf can provide more information about an
+ ELF file than is provided by objdump. In particular it can display DWARF
+ debugging information which (at the moment) objdump cannot. */
