It is not a comment to the user. It is a magic number that is looked for
 (at a binary level) by the shell. Everything after the magic number up
to a linefeed is used to build a string that the shell will use to
execute the script (with the script being the the first argument argv[1]
to that binary)

The fact that it is a script is only that it is executed. Otherwise,
it's just a textual file.
