+This library provides support for [BGZF][] (Blocked GZip Format) in
+Ruby. BGZF, originally defined as part of the [SAM/BAM][]
specification, is used to compress record-oriented bioinformatics data
in a way that facilitates random access, unlike plain gzip. A BGZF
file consists of contatenated 64 KB blocks, each an independent gzip
stream. It can be decompressed in its entirety with gzip, but this
library enables random access using 'virtual offsets' as defined in
