Check if a version number satisfies a version requirement.

Relation Parser

type RelParser a = CharParser () a Source

class ParseRelations a where Source

Methods parseRelations :: a -> Either ParseError Relations Source parseRelations parse a debian relation (i.e. the value of a Depends field). Return a parsec error or a value of type Relations Instances ParseRelations String ParseRelations ByteString
