The package defines the command \eolgrab that reads an string terminated by end of line, and then calls a macro with that string as argument. Thus

\eolgrab\section My title

is equivalent to

\section{My title}

A second command \eolgrabopt provides the string as an optional argument (which is useful for \item, for example).
