+%% DESCRIPTION:
+%%   multido.tex/multido.sty contains a loop macro, \multido, that supports
+%%   fixed-point addition and has a nice interface. Among other things, it
+%%   is useful for pictures and putting numbers on axes. multido.tex
+%%   is compatible with most TeX macro packages, including Plain TeX, LaTeX,
+%%   AmSTeX, and Ams-LaTeX.
+%%
+%% INSTALLATION:
+%%   Put this file where your TeX looks for inputs, under the name multido.tex.
+%%   Use the file multido.sty with LaTeX.
+%%
+%% DOCUMENTATION:
+%%   See multido.doc.
+%%
+%% COPYING:
+%%   Copying of part or all of this file is allowed under the following
+%%   conditions only:
+%%   (1) You may freely distribute unchanged copies of the file. Please
+%%       include the documentation when you do so.
+%%   (2) You may modify a renamed copy of the file, but only for personal
+%%       use or use within an organization.
+%%   (3) You may copy fragments from the file, for personal use or for
+%%       distribution, as long as credit is given where credit is due.

+%% CODE:
+% These macros use TeX primitives, plus the Plain TeX commands:
+%   \dimen@, \dimen@i, \count@, \newcount, \newtoks, \@ne, \tw@, \@z@.
+%
+% Check if file is loaded, announce file on terminal, and take care of @:

+% are also used as scratch counters.

+% This is probably pretty close to optimal, given the requirements that
