Helper Functions
checkVersionReq :: Maybe VersionReq -> Maybe DebianVersion -> BoolSource
Check if a version number satisfies a version requirement.
Relation Parser
type RelParser a = CharParser () aSource
class ParseRelations a whereSource
parseRelations :: a -> Either ParseError RelationsSource
parseRelations
parse a debian relation (i.e. the value of a
Depends field). Return a parsec error or a value of type
Relations
