 problems with the current solution are:
 1. information is duplicate. once in POM's dependencies and once in the
 maven.multiproject.includes property.
 2. it works without problems only for projects with relative paths, e.g., from
 one CVS repository.. for projects from multiple SCM repositories it's harder
 to maintain the same relative links on all developer computers.

        Files.createDirectories(userConf);
        Path userExtensions = userConf.resolve("settings.xml");

We can do better...

## What makes a dependency { #what-makes-a-dependency }

Up to now you have seen dependencies declared as functions.

But that's not the only way to declare dependencies (although it would probably be the more common).

The key factor is that a dependency should be a "callable".

A "**callable**" in Python is anything that Python can "call" like a function.

	if _, ok := err.(BucketPolicyNotFound); !ok {
		internalLogIf(GlobalContext, err, logger.WarningKind)
	}

	// As policy is not available for given bucket name, returns IsOwner i.e.
	// operation is allowed only for owner.
	return args.IsOwner
}

// NewPolicySys - creates new policy system.
func NewPolicySys() *PolicySys {
	return &PolicySys{}
}

// that the S3 client hasn't sent an ETag = MD5(object) and
// the backend can pick an ETag value.
func (key ObjectKey) SealETag(etag []byte) []byte {
	if len(etag) == 0 { // don't encrypt empty ETag - only if client sent ETag = MD5(object)
		return etag
	}
	var buffer bytes.Buffer
	mac := hmac.New(sha256.New, key[:])
	mac.Write([]byte("SSE-etag"))

            assertEquals(0, SMBUtil.readInt2(buffer, 2)); // Lock count
            assertArrayEquals(testFileId, Arrays.copyOfRange(buffer, 8, 24));
            assertEquals(24, bytesWritten); // Only structure, no locks
        }
