* @macro SEQAN_ENABLE_PARALLELISM

* @brief Indicates whether parallelism is enabled with value 0/1.

* By default, set to 1 if <tt>_OPENMP</tt> is defined and set to 0 otherwise.

* @section Examples
*
* If you want to change tihs value then you have to define this value before include any SeqAn header.
