In general, the format of a changelog varies dramatically, but the
GNU coding standards specify that a changelog is organized as blocks that each identify when a change was made and by whom (name and email address) and describes each change within a function or file. Between the date and the name, and between the name and the email address, there are two spaces. It is common to enclose the email address in < and >. The
Emacs editor creates such entries when creating additional changelog entries. For example: ==See also==
