+[B<-B>|B<--font-smoothing-threshold> I<size>]
+
+(this gets ignored in 1.3 for now!)
+
+This specifies the largest font size which will be rendered
+bitmapped, that is, without any font smoothing. By default,
+no text is rendered bitmapped.
+
+[B<-P>|B<--pango-markup>]
+
+All text in RRDtool is rendered using Pango. With the B<--pango-markup> option, all
+text will be processed by pango markup. This allows to embed some simple html
+like markup tags using
+
+ <span key="value">text</span>
+
+Apart from the verbose syntax, there are also the following short tags available.
+
+ b Bold
+ big Makes font relatively larger, equivalent to <span size="larger">
+ i Italic
+ s Strikethrough
+ sub Subscript
+ sup Superscript
+ small Makes font relatively smaller, equivalent to <span size="smaller">
+ tt Monospace font
+ u Underline
+

+
+[B<-G>|B<--graph-render-mode> {B<normal>,B<mono>}]
+
+There are 2 render modes:
+
+B<normal>: Graphs are fully Anti-aliased (default)
+
+B<mono>: No Anti-aliasing
+
+[B<-E>|B<--slope-mode>]
+
+RRDtool graphs are composed of stair case curves by default. This is in line with
+the way RRDtool calculates its data. Some people favor a more 'organic' look
+for their graphs even though it is not all that true.
+
+[B<-a>|B<--imgformat> B<PNG>|B<SVG>|B<EPS>|B<PDF>]
+
+Image format for the generated graph. For the vector formats you can
+choose among the standard Postscript fonts Courier-Bold,
+Courier-BoldOblique, Courier-Oblique, Courier, Helvetica-Bold,
+Helvetica-BoldOblique, Helvetica-Oblique, Helvetica, Symbol,
+Times-Bold, Times-BoldItalic, Times-Italic, Times-Roman, and ZapfDingbats.
+
+[B<-i>|B<--interlaced>]
+
+(this gets ignored in 1.3 for now!)
+
+If images are interlaced they become visible on browsers more quickly.
