Access A VMware Virtual Disk from Linux

Recently I needed to recover some data off a VMware Workstation virtual disk using Linux. As you probably know, VMware Workstation (and VMware vSphere) represents a physical disk by a virtual disk whose backing store is one or more VMDK files. VMDK (Virtual Machine Disk) is a documented file format, which uses the file extension .vmdk.
