Java class `ezvcard.Ezvcard` currently parses file _ez-vcard.properties_ to initialize constant values (`VERSION`, `GROUP_ID`, `ARTIFACT_ID` and `URL`). However, we could easily get these values from file _MANIFEST.MF_ . Example to retreive project version: ``` java VERSION = Ezvcard.class.getPackage().getImplementationVersion(); ``` Have you already studied this solution?
