Can you apply the verbage that must be represented by the symbols in Racket
regexp documentation shown below:

;;= means what?

| means what?

<pces> means what?

---------------------------------------------------------------------------



‹*regexp*›

 ::=

‹*pces*›



Match ‹*pces*›





|

‹*regexp*›|‹*regexp*›



Match either ‹*regexp*›, try left first

 Thanks!
