108 Blosxom Plug-in: chrono_nav
112 Populates the prevnexstory namespace with links for pointing to preceding
113 and following stories (arranged chronologically). I suggest you use it with interpolate_fancy for testing whether $prevnextstory::prevlink and $prevnextstory::nextlink are defined to avoid spurious links to appear when there is no older or fresher story.
117 Drop this plugin into your plugin directory. Place substitution
118 variables $prevnextstory::prevlink and $prevnextstory::nextlink in your flavour file as an href value for an anchor element. You can also use $prevnextstory::prevtitle and $prevnextstory::nextlink to get the titles of those stories, and $prevnextstory::prevdate and $prevnextstory::nextdate to get their publication dates. If you need the dates, you will have to adapt the @monthname and @monthabbr lists to your needs, and in some cases modify the formatting performed by the make_list subroutine (default date format is DD/MM/YYYY, with month names in French).
124 Version number is the date on which this version of the plug-in was created.
128 2006-01-01blosxom2 : take into account the corrections of $path_info in recent versions of blosxom.cgi
130 2004-08-22blosxom2 : First published version
