vc-dwim is a tool that simplifies the task of maintaining a ChangeLog and
using version control at the same time, for example by printing a reminder
when a file change has been described in the ChangeLog but the file has not
been added to the VC.  vc-chlog scans changed files and generates
standards-compliant ChangeLog entries based on the changes that it detects.")
