+ * Cross-endian support added by David Schleef <ds@schleef.org>.
+ *
+ * Major architectural rewrite by Erik Andersen <andersen@codepoet.org>
+ * to allow support for making hard links (though hard links support is
+ * not yet implemented), and for munging file permissions and ownership
+ * on the fly using --faketime, --squash, --devtable. And I plugged a
+ * few memory leaks, adjusted the error handling and fixed some little
+ * nits here and there.
+ *
+ * I also added a sample device table file. See device_table.txt
+ * -Erik, September 2001
+ *
+ * Cleanmarkers support added by Axis Communications AB
+ *
+ * Rewritten again. Cleanly separated host and target filsystem
+ * activities (mainly so I can reuse all the host handling stuff as I
+ * rewrite other mkfs utils). Added a verbose option to list types
+ * and attributes as files are added to the file system. Major cleanup
+ * and scrubbing of the code so it can be read, understood, and
+ * modified by mere mortals.
