| michael@0 | 9 | * Version strings are dot-separated sequences of version-parts. |
| michael@0 | 10 | * |
| michael@0 | 11 | * A version-part consists of up to four parts, all of which are optional: |
| michael@0 | 12 | * |
| michael@0 | 13 | * <number-a><string-b><number-c><string-d (everything else)> |
| michael@0 | 14 | * |
| michael@0 | 15 | * A version-part may also consist of a single asterisk "*" which indicates |
| michael@0 | 16 | * "infinity". |
| michael@0 | 17 | * |
| michael@0 | 18 | * Numbers are base-10, and are zero if left out. |
| michael@0 | 19 | * Strings are compared bytewise. |
| michael@0 | 20 | * |
| michael@0 | 21 | * For additional backwards compatibility, if "string-b" is "+" then |
| michael@0 | 22 | * "number-a" is incremented by 1 and "string-b" becomes "pre". |
| michael@0 | 23 | * |
| michael@0 | 24 | * 1.0pre1 |
| michael@0 | 25 | * < 1.0pre2 |
| michael@0 | 26 | * < 1.0 == 1.0.0 == 1.0.0.0 |
| michael@0 | 27 | * < 1.1pre == 1.1pre0 == 1.0+ |
| michael@0 | 28 | * < 1.1pre1a |
| michael@0 | 29 | * < 1.1pre1 |
| michael@0 | 30 | * < 1.1pre10a |
| michael@0 | 31 | * < 1.1pre10 |
| michael@0 | 32 | * |
| michael@0 | 33 | * Although not required by this interface, it is recommended that |
| michael@0 | 34 | * numbers remain within the limits of a signed char, i.e. -127 to 128. |
