+/* The numeric version format is AAAAABBBBBCCCCCDDDE where:
+ *
+ * AAAAA - major version number
+ * BBBBB - minor version number
+ * CCCCC - bugfix version number
+ * DDD   - alpha / beta (DDD + 500) version number
+ * E     - final (0) / snapshot (1)
+ *
+ * When DDDE is not 0, 1 is subtracted from AAAAABBBBBCCCCC. For example:
+ *
+ * Version      AAAAABBBBBCCCCCDDDE

+ * 0.1.0        0000000001000000000
