It was originally created for parsing .a files and getting the mod date as a hex number from the BSD object info. I needed a tool that could verify a debug map that used .a files. There are build scenarios where people are seeing LLDB not load .o files from .a files and they don't know why. This installs an LLDB command that can be used to verify all of the .o files in a debug map and reports if they are all ok, or if any are out date, missing, wrong in the .a file, missing from the .a file, etc. You can't use llvm-objdump or llvm-readobj for this task. 

It can also extract individual .o files from a .a file.

It can also find a symbol in the __.SYMDEF to tell you which .a file contains a symbol by name.
