 The package provides a set of commands `\NewOdvVariant`, `\NewPdvVariant` etc. that can be used to define a variant of a derivative. The package have already defined several derivatives:

-	When using the option \keyval{sort-method}{\{...\}}, the number of algorithms determines the number of layers e.g. \keyval{sort-method}{sign,symbol} is a sorting method with two layers, where the algorithms \val{sign} and \val{symbol} are applied in layer \num{1} and layer \num{2}, respectively. It should be understood as that the \val{sign} algorithm splits the terms into two groups, one with positive terms and one with negative terms. Then the \val{symbol} algorithm will order the terms within each groups according to the terms symbolic length. The mixed order is then formed by combining these two groups such that the positive terms comes first.

 	The next subsubsection is dedicated to give some examples of how the algorithms in this package sorts the mixed order.
 
 	\subsubsection{Examples}
 	The examples are constructed of a partial derivative with the comma separated list of orders given by \texttt{[3a-3hh-2b, 4c+4gg+2ff, -5d-5ee]} and a close up view of the mixed order. Square brackets are used to indicate grouping of terms and the text below a group refers to the algorithm applied. Here the words positive and negative, long and short, and big and low refers to the \val{sign}, \val{symbol}, and \val{abs} algorithms, respectively. A row of square brackets represents a layer.
 
-	The packages default sorting method is \keyval{sort-method}{sign,symbol,abs}, which is used below. The \val{sign} algorithm separate the positive and negative terms in the first layer. While in the second layer, the terms are separated by symbol length etc.
