The line of code that starts everything and blames nothing.

means The entry point of a program — the function that runs first and kicks off everything else.

from From Latin 'manus' (hand), which gave Old French 'main' meaning hand, and by extension 'principal' or 'chief' — the hand that holds control. English borrowed this sense of 'chief, principal, most important' (as in 'main road' or 'main point') centuries before programmers in the C tradition borrowed the word again, naming the one function every program must have: the starting hand that sets everything else in motion.
