This is basic sed scripting.

-ne means "don't print, execute the following code".

/.../ should be clear, { starts a "function list"
s// is "match last regexp, so s/// is "match last regexp and replace with empty string.
flag "p" to function "s" means "print if matched"
q is "quit".

that's really straight forward and all documented in my sed(1).
