Used to warn when your package dependencies don't match your semver policy. Helps w/ enforcing a particular dependency version policy.
Haven't tested a single wildcard ('*'), but if you have that in your dependencies you probably don't need something like this!
Determine what your policy is (e.g. X.Y.*, where you will only get new patch-level versions). Then test it against a package.json:
var semverify = require('semverify');semverify.process("package.json", "X.Y.*").pipe(process.stdout);
See gulp-semverify for gulp integration.
