function Get-ObjDump
{
<#
.SYNOPSIS

    Displays information about one or more Windows object files.

    PowerSploit Function: Get-ObjDump
    Author: Matthew Graeber (@mattifestation)
    License: BSD 3-Clause
    Required Dependencies: None
    Optional Dependencies: None

.DESCRIPTION

    Get-ObjDump parses and returns nearly identical infomation as the dumpbin
    utility. By nature of Get-ObjDump returning objects though, it lends itself
    much better to manipulation since every field is an object.

.PARAMETER Path

    Specifies a path to one or more object file locations.

.EXAMPLE

    C:\PS>Get-ObjDump -Path main.obj

.EXAMPLE

    C:\PS>ls *.obj | Get-ObjDump

.EXAMPLE

    C:\PS>$ObjectFile = Get-ObjDump -Path shellcode.obj
    C:\PS>$CodeBytes = $ObjectFile.SectionHeaders | ? {$_.Name -eq '.text'} | % {$_.RawData}

    Description
    -----------
    Pulls the raw bytes out of the text section. Note that in this form,
    no relocations have been fixed up.

.INPUTS

    System.String[]

    You can pipe a file system path (in quotation marks) to Get-ObjDump.

.OUTPUTS

    COFF.OBJECT_FILE

.LINK
