Forget "%options", this is just the macro for expanding the "%option"
in "%description". You only have to care about "%option", of course.

Anyway, the syntax is:

%option <variable> <value>
%options [-p<padding>]

where "%option <variable> <value>" is syntactically equivalent with
"%ifndef <variable> %define <variable> <value> %endif" plus remembering
the string "%option <variable> %{<variable>}" in an internal macro.
Then "%options" expands this internal macro back into the "%option
<variable> <value>" strings. If a <padding> is given, the <variable>
part in "%option <variable> <value>" is padding with spaces to a fixed
width in order to get a nice aligned output in %description texts.
