domain specific language (DSL) for processing the VCF format

 Bio-vcf provides a domain specific language (DSL) for processing the
 VCF format. Record named fields can be queried with regular
 expressions, e.g.
 .
  sample.dp>20 and rec.filter !~ /LowQD/ and rec.tumor.bcount[rec.alt]>4
 .
 Bio-vcf is a new generation VCF parser, filter and converter. Bio-vcf
 is not only very fast for genome-wide (WGS) data, it also comes with a
 really nice filtering, evaluation and rewrite language and it can
 output any type of textual data, including VCF header and contents in
 RDF and JSON.
