A new environment "singlespace" is provided, within which single % spacing will apply. % JFL - changed so that it works in regular text and so that vertical % space is before and after is correctly computed % 2. Double spacing is turned off within footnotes and floats (figures % and tables). % 3. Proper double spacing happens below tabular environments and in other % places where LaTeX uses a strut. % 4. Slightly more space is inserted before footnotes. % 5. JFL - fixes spacing before and after displayed math % % Note: This version sets a baselinestretch of 2. If this is too much, % put \setstretch{1.7} (or some appropriate value) before the % \begin{document} command. To print the document with single spacing % again, without removing "singlespace" environments, just put a % \setstretch{1} at the top of the document. % % PLEASE REPORT ANY BUGS % % Modified by: Jean-Francois Lamy % lamy@ai.toronto.edu % lamy@utai.uucp % % Author: Stephen Page -- sdpage@prg.oxford.ac.uk % sdpage%prg.oxford.ac.uk@cs.ucl.ac.uk % % Release date: 6 July 1986 - September 3, 1986 % % Known bugs: % .
