const mySchema = s.schema(myShape)

type MySchema = typeof mySchema.Output
// --> {

// 	 version: string
// 	 license?: string
// 	 dependencies: {
// 	 	 '@voltiso/schemar': string
// 	 }
// }

type MySchemaInput = typeof mySchema.Input

//   version: string;
//   license?: string | undefined;
//   dependencies?: {
//     "@voltiso/schemar"?: string | undefined;
//   } | undefined;
// }
