6 | % Sep 16, 1994 | |
7 | % version 1.4: Correction for use with \reversemargin | |
8 | % Sep 29, 1994: | |
9 | % version 1.5: Added the \iftopfloat, \ifbotfloat and \iffloatpage commands | |
10 | % Oct 4, 1994: | |
11 | % version 1.6: Reset single spacing in headers/footers for use with | |
12 | % setspace.sty or doublespace.sty | |
13 | % Oct 4, 1994: | |
14 | % version 1.7: changed \let\@mkboth\markboth to | |
15 | % \def\@mkboth{\protect\markboth} to make it more robust | |
16 | % Dec 5, 1994: | |
17 | % version 1.8: corrections for amsbook/amsart: define \@chapapp and (more | |
18 | % importantly) use the \chapter/sectionmark definitions from ps@headings if | |
19 | % they exist (which should be true for all standard classes). | |
20 | % May 31, 1995: | |
21 | % version 1.9: The proposed \renewcommand{\headrulewidth}{\iffloatpage... | |
22 | % construction in the doc did not work properly with the fancyplain style. | |
23 | % June 1, 1995: | |
24 | % version 1.91: The definition of \@mkboth wasn't restored on subsequent | |
25 | % \pagestyle{fancy}'s. | |
26 | % June 1, 1995: | |
27 | % version 1.92: The sequence \pagestyle{fancyplain} \pagestyle{plain} | |
28 | % \pagestyle{fancy} would erroneously select the plain version. | |
