/**
|
|
* 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.
