-=item -f, --field=(<number>|<regexp>)
+=item -f, --field=(<number> | <regexp>)
Compare values after a given number of whitespace separators,
or matching a regular expression.
Also changes an exponent I<1.602176634e-19> to I<160.2z>.
Short integers are aligned but kept without decimal point.
-=item -t, --interval[=(<seconds>|-<lines>)]
+=item -t, --interval[=(<seconds> | -<lines>)]
Output partial progress every given number of seconds or input lines.
An update can also be forced by sending a I<SIGALRM> alarm signal.
Override colors of parsed numbers.
Can be any CSI escape, such as I<90> for default dark grey,
-or alternatively I<1;30> for bold black.
+or alternatively I<1;30> for bright black.
In case of additional colors,
the last is used for values equal to the maximum, the first for minima.
If unspecified, these are green and red respectively (I<31 90 32>).
+Multiple intermediate colors will be distributed
+relative to the size of values.
-=item --spark[=<glyphs>]
+Predefined color schemes are named I<whites> and I<fire>,
+or I<greys> and I<fire256> for 256-color variants.
+
+=item --spark[=<characters>]
Replace lines by I<sparklines>,
single characters corresponding to input values.
