 History
 -------
 
+v0.1.1 passes the forgotten split argument and moves to using the new
+sub-command enabled bedtools. Thanks to David Leader.
+
 As of v0.1.0, the Galaxy tools uses a revised bam_to_bigwig.py script using
 genomeCoverageBed and bedGraphToBigWig - this approach allows gaps/skpis to
 be excluded from the coverage calculation, which is important for RNA-Seq.
