Some ideas are borrowed from existing tools (makedumpfile, crash). All
code is written from scratch, however.

The kdumpfile library itself is designed for use with any platform and
operating system. Xen is treated as just another type of operating
system. Based on which OS type is initialized, the library is able to
provide a hypervisor view or a Dom0 view.

There is another project led by Jeff Mahoney, which extends standard
gdb with semantic commands. This project supports only x86_64 Linux
right now. See https://github.com/jeffmahoney/crash-python.
