Originally written in 1992, the current version is 2.12r.
If invoked without arguments, cfdisk attempts to read the current partition table from the disk drive and present its findings.
One advantage of cfdisk (over fdisk for example) is that it's possible to enlarge an Extended Partition when there's free space after the partition. This is not directly possible with fdisk and some other partitioning software.
