+"""OCI Registry Helper
+
+Usage:
+    ocirh <subcommand> [<args>...]
+
+Subcommands:
+    repos           Lists repositories in the registry. Repos correspond to images
+                    pushed to the registry.
+    tags            Lists tags of the given repository.
+    manifests       Lists manifests of the given repository for the given tag.
+    rmi             Removes a tag from an image. If given tag is the only tag,
+                    removes the image.
+    gc              Runs garbage collection on the registry. Requires SSH public key
+                    access to registry server.
+    rmr             Removes given repository from the registry. Requires SSH public
+                    key access to registry server.
+
+Examples:
+    Suppose we have an image called 'fedora-toolbox' tagged with 'latest'.
+
+    ocirh repos
+    ocirh tags fedora-toolbox
+    ocirh manifests fedora-toolbox latest
+    ocirh rmi fedora-toolbox latest
+    ocirh gc

+# How this function works:
+#   If size_bytes == 0, returns 0 B.
+#   size_name is a tuple containing binary prefixes for bytes.
+#
+#   math.log takes the logarithm of size_bytes to base 1024.
+#   math.floor rounds down the result of math.log to the nearest integer.
+#   int ensures the result of math.floor is of type int, and stores it in i.
+#   The value of i is used to determine which binary prefix to use from
+#   size_name.
+#
+#   math.pow returns the value of 1024 raised to the power of i, stores it in p.
+#
+#   round takes the value of size_bytes, divides it by p, and stores the result
+#   in s at precision of 2 decimal places.
+#
+#   A formatted string with size s and binary prefix size_name[i] is returned.
