	<help>
Merge two input genomic coordinates iff they are exactly the same. If two or more genomic coordinates are merged, the tag **nbElements** is updated accordingly. As a consequence, all the reads which are exactly the same appear as one genomic coordinate.

This is especially useful for short RNA sequencing (where you want to count the number of read per miRNA, siRNA, etc.) or 5' capped short reads.
