Dependency.versionSpec

Sets/gets the matching version range as a specification string.

The acceptable forms for this string are as follows:

• "1.0.0" - a single version in SemVer format
• "==1.0.0" - alternative single version notation
• ">1.0.0" - version range with a single bound
• ">1.0.0 <2.0.0" - version range with two bounds
• "~>1.0.0" - a fuzzy version range
• "~>1.0" - a fuzzy version range with partial version
• "~master" - a branch name
• "*" - match any version (see also any`)

Apart from "<" and ">", ">=" and "<=" are also valid comparators.
