 /*!  \brief Abstract common class for mergers
 
-It defines only common interface of access to sources and operation merge(); The result of merging is available via function merger()
+Merging is defined as a combination of information from \c source pdfs into a single pdf called the \c merger.
+
+\f[
+f_{merged}(x) \leftarrow {f_1(x),f_2(x),f_3(x)}
+\f]
+
+In the basic form, the random variables of all source pdfs must be identical, e.g. \f$ x \f$ from the example above.
+
+Extension of the merger to a more demanding scenarios with fragmental sources is available in offspring bdm::merger_mix.
+
+This abstract class defines only the interface to using merger: operation merge(), and operation merger() which returns the result.
