Raises Safe_exception if the string isn't a valid version

#

val to_string : t -> string

val make_range_restriction : string option -> string option -> version_expr

make_range_restriction x y returns a test for versions where x <= version < y.

#

val parse_expr : string -> version_expr

parse_expr expr is a test for versions that match expr. e.g. parse_expr "2.2..!3 | 3.3.." matches 2.3.1 and 3.3.2 but not 3.1.

#

val strip_modifier : t -> t

Remove everything from the first "-"
