ikiwiki-calendar creates pages that use the ikiwiki/directive/calendar
directive, allowing the archives to be browsed one month
at a time, with calendar-based navigation.
You must specify the setup file for your wiki. The pages will
be created inside its srcdir, beneath the archivebase
directory used by the calendar plugin (default "archives").
To control which pages are included on the calendars,
a ikiwiki/PageSpec can be specified. The default is
all pages, or the pages specified by the comments_pagespec
setting in the config file. A pagespec can also be specified
on the command line. To limit it to only posts in a blog,
use something like "posts/* and !*/Discussion".
It defaults to creating calendar pages for the current
year. If you specify a year, it will create pages for that year.
Specify a second year to create pages for a span of years.
Existing pages will not be overwritten by this command by default.
Use the -f switch to force it to overwrite any existing pages.
