" Vim filetype plugin file " Language: generic Changelog file " Maintainer: Nikolai Weibull " Latest Revision: 2007-05-06 " Variables: " g:changelog_timeformat (deprecated: use g:changelog_dateformat instead) - " description: the timeformat used in ChangeLog entries.

Then " it does the same as the local o described above. " Notes: " run 'runtime ftplugin/changelog.vim' to enable the global mapping for " changelog files.
