# braket – Dirac bra-ket and set notations

Provides macros to typeset bra-ket notation, as well as set
specifiers, with a single (“`|`”) or a double
(“`||`” or (“`\|`”)
vertical bar
specifier in between two bracketed parts. Each macro comes in a
fixed-size version and an expanding version.

If the package finds itself operating under
e-tex, it uses the extended primitive
`\middle` for more reliable results
