Comments
Comments in Erlang start with a percent character (%) and extend to the end of line. There are no block comments.
Note: You’ll often see double percent characters (%%) in code examples. Double percent marks are recognized in the Emacs erlang-mode and enable automatic indentation of commented lines.
