+"""Convert BAM files to BigWig file format in a specified region.
+
+Usage:
+    bam_to_wiggle.py <BAM file> [<YAML config>] [--outfile=<output file name>]
+
+The optional config file (not used by the Galaxy interface) is in YAML format
+and specifies the location of the binary tools.
+
+program:
+  bedtools_genomeCoverageBed: genomeCoverageBed
+  ucsc_bedGraphToBigWig: bedGraphToBigWig
+
+If not specified, these will be assumed to be present in the system path.
+
+The script requires:
+    pysam (http://code.google.com/p/pysam/)
+    genomeCoverageBed from BedTools (http://code.google.com/p/bedtools/)
+    bedGraphToBigWig from UCSC (http://hgdownload.cse.ucsc.edu/admin/exe/)
+If a configuration file is used, then PyYAML is also required (http://pyyaml.org/)
