% This is a personal customization of the LaTeX style files
% article (4/16/88) and report (5/26/88). The changes are
% described more fully in the document jeep.tex. Briefly
% the style
%
% 1. Changes the default page sizes to reflect the fact
% that most output will be on 8.5 x 11 inch paper.
%
% 2. Adds commands that allow the casual LaTeX to change
% the formats of chapter, section, and theorem heads.
%
% 3. Adds commands to number equations and theorems within
% sections or subsections.
%
% 4. Makes Lance Berc's three part headers and footers the
% default page style. Adds a macro to underline the
% header.
%
% 5. Changes the default numbering of enumerate to arabic.
% Adds a new enumeration environment in which the items
% are close together.
%
% 6. Adds a command to produce a compact table of contents.
%
% 7. Adds commands to produce symbolic footnote marks and
% equation labels.
%
% 8. Adds commands by John hobby that make \bigl, \bigr, etc.
% work properly.
%
% 9. Adds Lamport's alltt environment--a quasi-verbatim
% environment that recognizes TeX and LaTeX commands.
% Change the default page sizes.

% Add a new environment literatim which is like the verbatim
% environment except that \, {, and } have their usual meanings.
% Thus, other commands and environments can appear within an `literatim'
% environment. This is essentially Lamport's alltt environment
% (the two sentences above were lifted from his description)
% with the following additions. The old special commands $, &, ^,
% and _, are \$, \&, \^, and \_. The command \@ will produce
% a verbatim backslash. A nonoptional argument to the the
% environment specifies the comment character (preceeded by
% a backslash). The character thus taken can be produced by \`.
% If the argument is null, there is no comment character.
% (Nb., space remains an active character in equations, which
% can have some unusual side effects).
