%%%                        for University of California Ph.D. dissertations.
%%%			   It is a direct port to LaTeX2e from UCTHESIS
%%%			   v2.7 by Ethan V. Munson, with no changes other
%%%			   than those for compatibility.  The major modifictions
%%%			   are in the font selection commands in the option
%%%			   files uct1x.clo.
%%%
%%%			   UCTHESIS.STY v2.7 is based on the standard
%%%			   report.sty as modified by Mittelbach and Schopf in
%%%			   Jan 1992.  The primary differences are (1) the use
%%%			   of pseudo-double-spacing, except in certain special
%%%                        environments; and (2) the use of a 6 inch line
%%%                        with 4em paragraph indentation.  It is only
%%%			   intended for single-sided printing.  Double-sided
%%%			   printing may be possible, but you're on
%%%			   your own.
%%%
%%%                        I know of no bugs in this implementation,
%%%                        but would be happy to hear of any problems
%%%                        that arise with it.
%%%
%%%			   Version 2.x fixes a bug in the previous
%%%			   version of 20 Jun 1988.  The bug was that
%%%			   ``draft'' optional mode didn't work because of
%%%			   problems in handling optional arguments.
%%%                        This file does not seem to work with earlier
%%%                        versions of LaTeX (pre-Jan 1992).
%%%
%%%			   Version 2.3 includes a single-spaced
%%%			   tabular* environment.
%%%
%%%			   Version 2.4 sets \evensidemargin correctly
%%%			   for two-sided style.  It also adds new
%%%			   environments (\smalltabular and
%%%			   \scriptsizetabular) which produce tables
%%%			   with smaller fonts.  The obvious methods
%%%			   of producing small-font tables don't work
%%%			   in ucthesis style.
%%%
%%%			   Version 2.5 adds support for the \maketitle
%%%			   macro.
%%%
%%%			   Version 2.6 adds support for complete and
%%%			   correct front matter.  Some dead code was
%%%			   removed, too.
%%%
%%%                        Version 2.7 adds front matter support for
%%%                        thesis committees of more than 3 people
%%%                        and for a labeled signature line on the
%%%                        abstract page.
%%%
%%%			   Version 3.0 is a direct port of version 2.7
%%%			   to LaTeX2e.  The major revisions in ucthesis.cls
%%%			   are converting option processing to LaTeX2e
%%%			   conventions.  The uct1x files have been revised
%%%			   to use the new font selection commands.
%%%
%%%			   Version 3.1 makes the following changes:
%%%				``U of C at CAMPUS'' is now ``U of C, CAMPUS''
%%%				new degreesemester variable
%%%				roman numeral frontmatter begins with page i,
%%%					not iii
%%%				``acknowledgments'' not ``acknowledgements''
%%%
%%%			   Version 3.2 explicitly states the license as LPPL.
%%%
%%%			   Version 3.3 updates the class for formatting changes
%%%			   made in late 2009 and early 2010, fixes a few minor
%%%			   bugs, and changes the name to ucbthesis to reflect
%%%			   the fact that this class is specific to the Berkeley
%%%			   campus.
%%%
%%%			   Version 3.4 rewrites the class to build upon the
%%%			   memoir class (instead of the report class, which had
%%%			   been used previously).  It also switches Master's
%%%			   theses to single-spacing (and adds an ``oldmasters''
%%%			   option for theses submitted in 2011 and earlier).
%%%			   In addition, it added support for co-chairs on the
%%%			   dissertation/thesis committee, joint degrees, and
%%%			   degrees with a Designated Emphasis.
%%%
%%%			   Version 3.5 adds the designated emphasis to the
%%%			   abstract (which is required).
%%%
%%%			   Version 3.6 changes the title from bold font to
%%%			   regular and adjusts the spacing in the abstract page.
%%%			   It adds \cochairs to the documentation and makes some
%%%			   fixes and adds some material to the example thesis.
%%%
%%%			   A problem that some people have had is
%%%			   that you can't use \pagestyle{headings}
%%%			   and \markboth if you use \part.  The solution
%%%			   is to get the headerfooter style, which is
%%%			   nice and simple to use."
