Simple DSL to define parser for flat files formats common in biofinformatics, such as Swissprot, Uniprot, KEGG, TREMBL, etc. SwissParser API was changed in its version 1.0.0 to simplify parser definition. The code was tested on entire Uniprot and KEGG releases and functional testing guarantees that existing features will not break after an update.
