This module implements a parser for BLAST results.
This module is DEPRECATED. It is *very* recommended that you run blast with XML output instaed, and use the BlastXML module to parse it. Don't say I didn't warn you!
BLAST is a tool for searching in (biological) sequences for similarity. This library is tested against NCBI-blast version 2.2.14. There exist several independent versions, so expect some incompatbilities if you're using a different BLAST version.
The format is straightforward (and non-recursive), and this implementation uses a simple line-based, hierarchical parser.
