Initial Commit

This initial commit includes a directory deduplicator (for thinning out
Time Machine snapshots) and an automatic tool to detect and apply the
necessary metadata for a successful tmutil inherit (needed when you
want to use a backup drive with a new computer, for example).

+# tmimport
+    Time Machine Importer
+
+    tmimport.sh <backup drive>
+
+    Time Machine Importer modifies the metadata of a backup drive to match the 
+    current computer's model and unique identifiers (primary MAC address and
+    hardware platform UUID/provisioning UDID) and attempts to 'inherit' the
+    backup history.
+
+    The backup drive should be specified by disk or volume name (or path) or
+    the mount point of the backup drive. If Time Machine Importer cannot find
+    an appropriate disk volume or mount point, it will check to see if the 
+    specified directory is a valid Backups.backupdb location (or a machine
+    directory under one).
+
+    A future version may attempt to detect HFS+ or APFS partitions serving as
+    backup drives, and, if a backup drive is specified as a device path, it
+    will automagically choose the correct backup path.

+    Directory De-Duplication ("Dirty Dupe")
+
+    dirdedupe.sh [--execute] masterdir shadowdir
+
+    For each file in shadowdir, replace it with a hard link to the matching file
+    (if any) in masterdir.  A file will be considered a match if, and only if, it
+    shares the same file name, relative path, and contents.
+
+    OPTIONS
+
+       --execute  Actually remove and link duplicate files. By default, this 
+                  program runs in test mode.
