- port MANUAL to gem2rpm.yml

- updated to version 1.2.2
* Fix an error with duplicates being returned by Timezone#all_country_zones
and Timezone#all_country_zone_identifiers when used with tzinfo-data
v1.2014.6 or later.
* Use the zone1970.tab file for country timezone data if it is found in the
zoneinfo directory (and fallback to zone.tab if not). zone1970.tab was added
in tzdata 2014f. zone.tab is now deprecated.


Version 1.2.1 - 1-Jun-2014
--------------------------

* Support zoneinfo files generated with zic version 2014c and later.
* On platforms that only support positive 32-bit timestamps, ensure that
conversions are accurate from the epoch instead of just from the first
transition after the epoch.
* Minor documentation improvements.


Version 1.2.0 - 26-May-2014
---------------------------

* Raise the minimum supported Ruby version to 1.8.7.
* Support loading system zoneinfo data on FreeBSD, OpenBSD and Solaris.
Resolves #15.
* Add canonical_identifier and canonical_zone methods to Timezone. Resolves #16.
* Add a link to a DataSourceNotFound help page in the TZInfo::DataSourceNotFound
exception message.
