-# Script for uploading files to a Google Code project.
-#
-# This is intended to be both a useful script for people who want to
-# streamline project uploads and a reference implementation for
-# uploading files to Google Code projects.
-#
-# To upload a file to Google Code, you need to provide a path to the
-# file on your local machine, a small summary of what the file is, a
-# project name, and a valid account that is a member or owner of that
-# project.  You can optionally provide a list of labels that apply to
-# the file.  The file will be uploaded under the same name that it has
-# in your local filesystem (that is, the "basename" or last path
-# component).  Run the script with '--help' to get the exact syntax
-# and available options.
-#
-# Note that the upload script requests that you enter your
-# googlecode.com password.  This is NOT your Gmail account password!
-# This is the password you use on googlecode.com for committing to
-# Subversion and uploading files.  You can find your password by going
-# to http://code.google.com/hosting/settings when logged in with your
-# Gmail account. If you have already committed to your project's
-# Subversion repository, the script will automatically retrieve your
-# credentials from there (unless disabled, see the output of '--help'
-# for details).
-#
-# If you are looking at this script as a reference for implementing
-# your own Google Code file uploader, then you should take a look at
-# the upload() function, which is the meat of the uploader.  You
-# basically need to build a multipart/form-data POST request with the
-# right fields and send it to https://PROJECT.googlecode.com/files .
-# Authenticate the request using HTTP Basic authentication, as is
-# shown below.

-
-This script help you migrate from a 3.1 database to 3.2 and later
-
-Changes:
-* Created a new calendarinstances table to support calendar sharing.
-* Remove a lot of columns from calendars.
-
-Keep in mind that ALTER TABLE commands will be executed. If you have a large
-dataset this may mean that this process takes a while.
-
-Make a back-up first. This script has been tested, but the amount of
-potential variants are extremely high, so it's impossible to deal with every
-possible situation.
-
-In the worst case, you will lose all your data. This is not an overstatement.
-
-Lastly, if you are upgrading from an older version than 3.1, make sure you run
-the earlier migration script first. Migration scripts must be ran in order.

-     * object, based on contents of iCalendar properties, date-ranges and
-     * iCalendar component types (VTODO, VEVENT).
-     *
-     * This method should just return a list of (relative) urls that match this
-     * query.
-     *
-     * The list of filters are specified as an array. The exact array is
-     * documented by \Sabre\CalDAV\CalendarQueryParser.
-     *
-     * Note that it is extremely likely that getCalendarObject for every path
-     * returned from this method will be called almost immediately after. You
-     * may want to anticipate this to speed up these requests.
-     *
-     * This method provides a default implementation, which parses *all* the
-     * iCalendar objects in the specified calendar.
-     *
-     * This default may well be good enough for personal use, and calendars
-     * that aren't very large. But if you anticipate high usage, big calendars
-     * or high loads, you are strongly adviced to optimize certain paths.
-     *
-     * The best way to do so is override this method and to optimize
-     * specifically for 'common filters'.
-     *
-     * Requests that are extremely common are:
-     *   * requests for just VEVENTS
-     *   * requests for just VTODO
-     *   * requests with a time-range-filter on a VEVENT.
-     *
-     * ..and combinations of these requests. It may not be worth it to try to
-     * handle every possible situation and just rely on the (relatively
-     * easy to use) CalendarQueryValidator to handle the rest.
-     *
-     * Note that especially time-range-filters may be difficult to parse. A
-     * time-range filter specified on a VEVENT must for instance also handle
-     * recurrence rules correctly.
-     * A good example of how to interpret all these filters can also simply
-     * be found in \Sabre\CalDAV\CalendarQueryFilter. This class is as correct
-     * as possible, so it gives you a good idea on what type of stuff you need
-     * to think of.
-     *
-     * This specific implementation (for the PDO) backend optimizes filters on
-     * specific components, and VEVENT time-ranges.

-     * from collection.

-     * you only have to report changes that happened only directly in immediate

-     * below the child collections. (grandchildren)

-     * should be treated as infinite.
-     *
-     * If the limit (infinite or not) is higher than you're willing to return,
-     * the result should be truncated to fit the limit.
-     * Note that even when the result is truncated, syncToken must be consistent
-     * with the truncated result, not the result before truncation.

-/**
- * ICS Exporter.
- *
- * This plugin adds the ability to export entire calendars as .ics files.
- * This is useful for clients that don't support CalDAV yet. They often do
- * support ics files.
- *
- * To use this, point a http client to a caldav calendar, and add ?expand to
- * the url.
- *
- * Further options that can be added to the url:
- *   start=123456789 - Only return events after the given unix timestamp
- *   end=123245679   - Only return events from before the given unix timestamp
- *   expand=1        - Strip timezone information and expand recurring events.
- *                     If you'd like to expand, you _must_ also specify start
- *                     and end.
- *
- * By default this plugin returns data in the text/calendar format (iCalendar
- * 2.0). If you'd like to receive jCal data instead, you can use an Accept
- * header:
- *
- * Accept: application/calendar+json
- *
- * Alternatively, you can also specify this in the url using
- * accept=application/calendar+json, or accept=jcal for short. If the url
- * parameter and Accept header is specified, the url parameter wins.
- *
- * Note that specifying a start or end data implies that only events will be
- * returned. VTODO and VJOURNAL will be stripped.

-/**
- * CalDAV scheduling plugin.
- * =========================.
- *
- * This plugin provides the functionality added by the "Scheduling Extensions
- * to CalDAV" standard, as defined in RFC6638.
- *
- * calendar-auto-schedule largely works by intercepting a users request to
- * update their local calendar. If a user creates a new event with attendees,
- * this plugin is supposed to grab the information from that event, and notify
- * the attendees of this.
- *
- * There's 3 possible transports for this:
- * * local delivery
- * * delivery through email (iMip)
- * * server-to-server delivery (iSchedule)
- *
- * iMip is simply, because we just need to add the iTip message as an email
- * attachment. Local delivery is harder, because we both need to add this same
- * message to a local DAV inbox, as well as live-update the relevant events.
- *
- * iSchedule is something for later.
