| /** |
| * Version strings are dot-separated sequences of version-parts. |
| * |
| * A version-part consists of up to four parts, all of which are optional: |
| * |
| * <number-a><string-b><number-c><string-d (everything else)> |
| * |
| * A version-part may also consist of a single asterisk "*" which indicates |
| * "infinity". |
| * |
| * Numbers are base-10, and are zero if left out. |
| * Strings are compared bytewise. |
| * |
| * For additional backwards compatibility, if "string-b" is "+" then |
| * "number-a" is incremented by 1 and "string-b" becomes "pre". |
| * |
| * 1.0pre1 |
| * < 1.0pre2 |
| * < 1.0 == 1.0.0 == 1.0.0.0 |
| * < 1.1pre == 1.1pre0 == 1.0+ |
| * < 1.1pre1a |
| * < 1.1pre1 |
| * < 1.1pre10a |
| * < 1.1pre10 |
| * |
| * Although not required by this interface, it is recommended that |
| * numbers remain within the limits of a signed char, i.e. -127 to 128. |
