  I will discuss a few select aspects of the most common and best understood
galactic-scale outflow -- starburst-driven superwinds, focusing on winds from
nuclear starburst galaxies. I will show that modern observations, in particular
in the soft and hard X-ray bands, complement and reinforce the existing
paradigm of superwinds as flows collectively driven by multiple SNe. The
properties of the diffuse X-ray emission from dwarf starburst galaxies, L_BOL ~
L_* starbursts in spiral galaxies, and ULIRGS, are all consistent with
superwind activity. Where appropriate, I contrast the physics of
starburst-driven winds with poorly collimated winds from AGN, and discuss what
we know of the role of LLAGN and Seyfert nuclei in starburst superwind
galaxies.
