The module versioning

[Leonid Mesnik]

Hi 

Could you please point me to description of module version format.
I'm not able to sort out how to compare versions and use VersionQuery
now. 

For example I was able to compile and install these libraries:
However I don't know what should be correct order and what should be
only first library selected for for "=1.1"?

module jigsaw.library @ 1.1 {    
}

module jigsaw.library @ 01.1 {
}

module jigsaw.library @ 1.10 {
}

module jigsaw.library @ 1.01 {
}

module jigsaw.library @ 1.1.0 {
}

module jigsaw.library @ 1.1.0.0 {
}

Thank you,
Leonid
