NOTE: the postscript routines cmCTR cmshow cmstringwidth etc are in defscover.txt;
BEWARE: the -c (center) option of img2ps is broken;  it always positions image to top-left corner of page, so page-size bigger than image does nothing useful;

CHANGES:
2009-11-07:  revised interface between the 2 parts of mk-calendar:
	instead of writing coverFront.ps and coverBack.ps am now writing smallpage01.ps (front-cover), and smallpage32.ps (back-cover) -- for a 15-month calendar;
	this works better when wanting to make things like a 14-month calendar with smallpage{30,31}.ps as prose pages,
	or 12-monther with smallpage{26,27,28}.ps as prose and smallpage{29,30,31}.ps as notepad-like pages;
	ie: this script supplies all smallpages other than the IMG+CAL pairs;
2009-11-12:  published version:  text+logo-only, no photo;  use only fonts from the PS-standard-35; ComputerModern fonts are an awful choice for a lot of reasons...
	note: at least with ghostscript, a missing font gets replaced with Courier, rather than being fatal, but that still isn't great;
	switched to Times, except for my own use;
