The semver subcommands make use of semver (https://github.com/Masterminds/semver) to provide
tools for working with semantic version strings.

Use: "check",
Short: "Check version constraints",
Long: `Check version constraints
There are two elements to the comparisons. First, a comparison string is a list of space or comma separated AND comparisons.
These are then separated by || (OR) comparisons. For example, ">= 1.2 < 3.0.0 || >= 4.2.3" is looking for a comparison that's
greater than or equal to 1.2 and less than 3.0.0 or is greater than or equal to 4.2.3.

Example: `newrelic utils semver check --constraint ">= 1.2.3" --version 1.3`,
