" Vim filetype plugin file
" Language: generic Changelog file
" Maintainer: Nikolai Weibull <nikolai+work.vim@bitwi.se>
" Latest Revision: 2005-06-29
" Variables:
" g:changelog_timeformat -
" description: the timeformat used in ChangeLog entries.
" default: "%Y-%m-%d".
" g:changelog_username -
" description: the username to use in ChangeLog entries
" default: try to deduce it from environment variables and system files.
" Local Mappings:
" <Leader>o -
" adds a new changelog entry for the current user for the current date.
" Global Mappings:
" <Leader>o -
" switches to the ChangeLog buffer opened for the current directory, or
" opens it in a new buffer if it exists in the current directory. Then
" it does the same as the local <Leader>o described above.
" Notes:
" run 'runtime ftplugin/changelog.vim' to enable the global mapping for
" changelog files.
" TODO:
" should we perhaps open the ChangeLog file even if it doesn't exist already?
" Problem is that you might end up with ChangeLog files all over the place.
" If 'filetype' isn't "changelog", we must have been to add ChangeLog opener
