  10 // This is a tool similar to readelf, except it works on multiple object file
  11 // formats. The main purpose of this tool is to provide detailed output suitable
  12 // for FileCheck.
  13 //
  14 // Flags should be similar to readelf where supported, but the output format
  15 // does not need to be identical. The point is to not make users learn yet
  16 // another set of flags.
  17 //
  18 // Output should be specialized for each format where appropriate.
