% cmu-titlepage.sty created 2 November 1989 R. Harper and D. Long
% substyle for use with standard LaTeX article or report document styles
% adapted from titlepage.sty
%
% cmu-titlepage2.sty by Håkan Younes, Fall 2004:
%   - Removed DARPA funding clutter.  Just use generic \support command.
%   - Forced abstract to always be on the third page so that Catherine Copetas
%     does not have to edit PDF files.
%   - Adjusted position of title/author box (required by recent versions of
%     LaTeX to get the box at the same location as the cutout of the CMU tech
%     report cover.
%   - Added support for PhD theses: \committee, \dedication, and
%     \acknowledgments commands
%
% Example usage for tech reports, with 11pt times, fullpage, and caption2:
%
%   \documentclass[11pt,leqno]{article}
%   \usepackage{cmu-titlepage2}
%   \usepackage{fullpage}
%   \usepackage[small,bf]{caption2}
%   \usepackage{times}
