-1. A pre-release version number MAY be denoted by appending a dash and a
-qualifying string immediately following the patch version. The qualifying
-string is comprised of a mandatory identifier and an optional sequence number.
-If the sequence number is used, it MUST be separated from the identifier by a
-tilde. Identifiers MUST be comprised of only alphanumerics plus dash
-[0-9A-Za-z-]. Sequence numbers MUST be comprised of only digits [0-9].
-Pre-release versions satisfy but have a lower precedence than the associated
-normal version. Precedence SHOULD be determined by lexicographic ASCII sort
