Hi,

following discussion with upstream, this package is no more needed. Please 
reject it for now.

Would it be possible to make cyrus-imapd capable of using the standard
tzdata package instead of duplicating it in cyrus-timezones?

The tzdata package is often updated in Debian stable, how do you intend
to keep cyrus-timezones in sync with it?

Package: wnpp
Severity: wishlist
Owner: Xavier Guimard 

* Package name: cyrus-timezones
  Version : 0.0~git20190710.1a0107a
  Upstream Author : Cyrus-Imapd maintainers 
* URL : https://github.com/cyrusimap/cyrus-timezones
* License : GPL-2+

  Description : Timezone information for the Cyrus IMAP Server

cyrus-timezones provides timezone information for the Cyrus IMAP Server.
By use of the vzic timezone compiler it compiles VTIMEZONEs based on the
latest IANA timezone database (https://www.iana.org/time-zones).

The generated timezones are installed at /usr/share/cyrus-timezones/zoneinfo
and their absolute path is defined as a pkg-config variable:

$ pkg-config --variable=zoneinfo_dir cyrus-timezones

This library improves cyrus-imapd ≥ 3.2. I'm maintainer of cyrus-imapd
and will maintain this package.
