+ *
+ * CFDISK
+ *
+ * cfdisk is a curses based disk drive partitioning program that can
+ * create partitions for a wide variety of operating systems including
+ * Linux, MS-DOS and OS/2.
+ *
+ * cfdisk was inspired by the fdisk program, by A. V. Le Blanc
+ * (LeBlanc@mcc.ac.uk).
+ *

+ * Created: Fri Jan 28 22:46:58 1994, martin@cs.unc.edu
+ * >2GB patches: Sat Feb 11 09:08:10 1995, faith@cs.unc.edu
+ * Prettier menus: Sat Feb 11 09:08:25 1995, Janne Kukonlehto
+ * <jtklehto@stekt.oulu.fi>
+ * Versions 0.8e-p: aeb@cwi.nl
+ * Rebaptised 2.9p, following util-linux versioning.
+ *
+ * Recognition of NTFS / HPFS difference inspired by patches
+ * from Marty Leisner <leisner@sdsp.mc.xerox.com>
+ * Exit codes by Enrique Zanardi <ezanardi@ull.es>:
+ * 0: all went well
+ * 1: command line error, out of memory
+ * 2: hardware problems [Cannot open/seek/read/write disk drive].
+ * 3: ioctl(fd, HDIO_GETGEO,...) failed. (Probably it is not a disk.)
+ * 4: bad partition table on disk. [Bad primary/logical partition].
+ *
+ * Sat, 23 Jan 1999 19:34:45 +0100 <Vincent.Renardias@ldsol.com>
+ * Internationalized + provided initial French translation.
+ * Sat Mar 20 09:26:34 EST 1999 <acme@conectiva.com.br>
+ * Some more i18n.
+ * Sun Jul 18 03:19:42 MEST 1999 <aeb@cwi.nl>
+ * Terabyte-sized disks.
+ * Sat Jun 30 05:23:19 EST 2001 <nathans@sgi.com>
+ * XFS label recognition.
+ * Thu Nov 22 15:42:56 CET 2001 <flavio.stanchina@tin.it>
+ * ext3 and ReiserFS recognition.
+ * Sun Oct 12 17:43:43 CEST 2003 <flavio.stanchina@tin.it>
+ * JFS recognition; ReiserFS label recognition.
