But how does a version number which is "formless" tell Boost Build what 
to do ? As an example, suppose I write:

using msvc : 7-1 ;

instead of

using msvc : 7.1

since both are valid evidently because the version number can have any 
form I like. What does 7-1 or 7.1 mean to Boost Build ? What does it so 
with the information in the 'version' parameter ?
