== Description ==
Repeat something for ''start'', ''start + step'', ''start + 2*step'', ..., continuing until ''stop'' is exceeded.
== Example ==
<context source=yes>
Counting down:
\dostepwiserecurse{10}{4}{-2}
{\recurselevel...\ }
Counting stopped.
Counting down again:
\dostepwiserecurse{10}{5}{-2}
{\recurselevel...\ }
Counting stopped.
</context>
