% -- PrepageEnvironment ------------------------------------------------------
% (this code 'borrowed' for thesis91e.cls)
% PrepageEnvironment is used in frontmatter for abstract,
% acknowledgement etc. The first argument is a name of the new
% environment and the second one the title printed out for it.
%
% The PrepageEnvironment attempts to centre the text vertically on the
% page. If your text approaches or exceeds one page in length, you will
% probably find the title at the bottom of one page, and the text
% itself on the next page. To avoid this, remove the ``\null\vfil'' in
% the beginning and ending part of ``\newenvironment'', and latex
% won't try to centre it on the page.
