Methods Summary
protected voiddoLine(java.lang.String line)
Process one line from the current input

		tabPos = 0;
		// count leading (not imbedded) tabs.
		for (int i=0; i<line.length(); i++) {
			if (line.charAt(i)=='\t")
				tabPos++;
			else
				break;
		}
		String l = line.trim(); // removes spaces AND tabs
		if (l.length() == 0) {
			++lineNum;
			return;
		}
		moveTo(leftMargin + (tabPos * INCH),
			topMargin-(lineNum++ * leading));
		println('(" + toPSString(l)+ ") show");

		// If we just hit the bottom, start a new page
		if (curY <= botMargin)
			startPage();
public static voidmain(java.lang.String[] av)


	       
		if (av.length == 0) 
			new PSFormatter(
				new InputStreamReader(System.in)).process();
		else for (int i = 0; i < av.length; i++) {
			new PSFormatter(av[i]).process();
		}
protected voidmoveTo(int x, int y)

		curX = x;
		curY = y;
		println(x + " " + y + " " + "moveto");
protected voidprintln(java.lang.String s)

		System.out.println(s);
protected voidprocess()
Main processing of the current input source.


		String line;

		prologue();			// emit PostScript prologue, once.

		startPage();		// emit top-of-page (ending previous)

		while ((line = br.readLine()) != null) {
			if (line.startsWith("\f") || line.trim().equals(".bp")) {
				startPage();
				continue;
			}
			doLine(line);
		}

		// finish last page, if not already done.
		if (lineNum != 0)
			println("showpage");
voidprologue()

		println("%!PS-Adobe");
		println("/Courier findfont " + points + " scalefont setfont ");
protected voidstartPage()
Handle start of page details.

		if (pageNum++ > 0)
			println("showpage");
		lineNum = 0;
		moveTo(leftMargin, topMargin);
protected java.lang.StringtoPSString(java.lang.String o)
Overly-simplistic conversion to PS, e.g., breaks on "foo\)bar"

		StringBuffer sb = new StringBuffer();
		for (int i=0; i<o.length(); i++) {
			char c = o.charAt(i);
			switch(c) {
				case '(":	sb.append("\\("); break;
				case ')":	sb.append("\\)"); break;
				default:	sb.append(c); break;
			}
		}
		return sb.toString();
