Omar is looking for:
- A tool that generates a zip containing files in "new" that aren't in "old"
(that would effectively act like a "patch" that doesn't delete removed files).
Here's what butler does:

Here's what butler does:
Suppose we want to compute the frequency spectrum of an n-point sampled signal. That is, | |
we want to compute the signal's discrete Fourier transform. Taking a cue from multi-rate | |
signal processing, let's try a divide-and-conquer approach where we downsample the signal | |
by 2:1 and recursively compute the spectrum of that. There are two possible downsamplings, | |
corresponding to the even and odd phases. | |
By the Nyquist sampling theorem, assuming the signal has no upper half-band frequencies, | |
i.e. its top n/2 frequency bins are zero, the spectrum can be perfectly reconstructed | |
from the spectrum of _either_ the even subsignal or the odd subsignal, without any aliasing. |

Unlike using VMWare Tools to enable Linux guest capabilities, the open-vm-tools
package doesn't auto-mount shared VMWare folders. This can be frustrating in various ways, but there's an easy fix.
Install open-vm-tools
and run:
sudo mount -t fuse.vmhgfs-fuse .host:/ /mnt/hgfs -o allow_other
