+ * A.V. Le Blanc (LeBlanc@mcc.ac.uk) wrote Linux fdisk 1992-1994,
+ * patched by various people (faith@cs.unc.edu, martin@cs.unc.edu,
+ * leisner@sdsp.mc.xerox.com, esr@snark.thyrsus.com, aeb@cwi.nl)
+ * 1993-1995, with version numbers (as far as I have seen) 0.93 - 2.0e.
+ * This program had (head,sector,cylinder) as basic unit, and was
+ * (therefore) broken in several ways for the use on larger disks -
+ * for example, my last patch (from 2.0d to 2.0e) was required
+ * to allow a partition to cross cylinder 8064, and to write an
+ * extended partition past the 4GB mark.
+ *
+ * Karel Zak wrote new sfdisk based on libfdisk from util-linux
+ * in 2014.
