python3-gffutils 0.10.1-2 (armhf binary) in ubuntu impish

 A Python package for working with and manipulating the GFF and GTF format
 files typically used for genomic annotations. Files are loaded into a
 sqlite3 database, allowing much more complex manipulation of hierarchical
 features (e.g., genes, transcripts, and exons) than is possible with
 plain-text methods alone.
