\long\def\@makefntext#1{\parindent 1em\noindent

%% \@makefntext is *supposed* to use \@makefnmark, but article.sty
%%      copies the definition of \@makefnmark instead of using it.
%%      This defeats the possibility of customization of mark separate
%%      from customization of text.  Thus the following small
%%      on the definition in article.sty:
%%
% \@makefnmark : A macro to generate the footnote marker that goes
%                in the text.  Default definition used.

%%
%%  \nofootnotemark, placed before \footnotetext[1]{text}, causes
%%  the footnote to be set without a mark (even at the bottom of the
%%  page).  Should be enclosed in a group, so it doesn't affect later
%%  footnotes.
%%
\newcommand{\nofootnotemark}{\let\@makefnmark\relax}

%% \nothanks{text} creates a footnote like \thanks, but without
%%  a footnote mark of any kind (either here or at the bottom of
%%  the page).
