% Changes by Beach, May 20, 1983 2:07 pm
% Add new StyleRules: abstract - for BlueAndWhite abstracts, authors - for BlueAndWhite authors, block - to differentiate between block-style paragraphs and indent-first-line paragraphs
% Modify StyleRules: body - an indent-first-line paragraph, * - modify StyleRules which depend on block vs body, reference - make hanging indent work correctly with tab, root - establish page margins for header/footers
% Modify Cedar.Style parameters to be executable rather than local variables. This permits styles to redefine them and have the effects percolate all affected StyleRules.
