-* `family` is a String representing the system's libc family.
-* `version` is a String representing the system's libc version.
+* `GLIBC` is a String containing the value "glibc" for comparison with `family`.
+* `MUSL` is a String containing the value "musl" for comparison with `family`.
+* `family` is a String representing the system libc family.
+* `version` is a String representing the system libc version number.
