"description": "A *Version Range* a range of versions that **may** be present or installed to fulfill dependencies.\n\nA Version Range of the number `0` indicates all available versions. No other number values are allowed.\n\nOften a Version Range is just a single version. For a [SemVer](https://semver.org), for example, `2.4.2` means that **at least** version 2.4.2 must be present.\n\nAlternatively, a version range **may** use the operators `<` (less than), `<=` (less than or equal), `>` (greater than), `>=` (greater than or equal), `==` (equal), and `!=` (not equal). For example, the specification `< 2.0` means that any version less than version 2.0 is suitable.\n\nFor more complicated situations, version specifications **may** be AND-ed together using commas. The specification `>= 1.2.0, != 1.5.2, < 2.0.0` indicates a version that must be **at least** 1.2.0, **less than** 2.0.0, and **not equal to** 1.5.2.",
