Log message:
python/wheel.mk: simplify a lot, and switch to 'installer' for installation

This follows the recommended bootstrap method (flit_core, build, installer).

However, installer installs different files than pip, so update PLISTs
for all packages using wheel.mk and bump their PKGREVISIONs.

Log message:
py-tzlocal: updated to 5.2

5.2 (2023-10-22)
- Added a pre-commit config
- Updated python versions [hugovk]
- Added type hints for the public functions
- Moved to using pyproject.toml for project config.

Log message:
py-tzlocal: updated to 5.1

5.1 (2023-10-04)
----------------
- The Unicode data doesn't change tz names when IANA does, so what is current
  in IANA is treated as an alias in Unicode data. This version handles that.

Log message:
py-tzlocal: update to 5.0.1.

5.0.1 (2023-05-15)
------------------

- The logging info under windows made it look like it looked up the registry
  info even when you had a TZ environment, but it doesn't actually do that.

- Improved the handling of loggers.

5.0 (2023-05-14)
----------------

- Fixed a bug in the new assert_tz_offset method.

5.0b2 (2023-04-11)
------------------

- Change how the system offset is calculated to deal with non-DST
  temporary changes, such as Ramadan time in Morocco.

- Change the default to only warn when the timezone offset and system
  offset disagree (but still not even warn if TZ is set)

- Add the assert_tz_offset() method to the top level for those who want
  to explicitly check and fail.

5.0b1 (2023-04-07)
------------------

- Removed the deprecation shim.

4.4b1 (2023-03-20)
------------------

- Added debug logging

Log message:
py-tzlocal: update to 4.3.

4.3 (2023-03-18)
----------------

- Improved the error message when the ZoneInfo cannot be found

- Don't error out because we find multiple possible timezones for
  a symlink.

- More stable on Android/Termux with proot

4.2 (2022-04-02)
----------------

- If TZ environment variable is set to /etc/localhost, and that's a link to
  a zoneinfo file, then tzlocal will now find the timezone name, and not
  just return a localtime TZ object.

4.1 (2021-10-29)
----------------

- No changes from 4.1b1.

4.1b1 (2021-10-28)
------------------

- It turns out a lot of Linux distributions make the links between zoneinfo
  aliases backwards, so instead of linking GB to Europe/London it actually
  links the other way. When /etc/localtime then links to Europe/London, and you
  also have a config file saying Europe/London, the code that checks if
  /etc/localtime is a symlink ends up at GB instead of Europe/London and
  we get an error, as it thinks GB and Europe/London are different zones.

  So now we check the symlink of all timezones in the uniqueness test. We still
  return the name in the config file, though, so you would only get GB or Zulu
  returned as the time zone instead of Europe/London or UTC if your only
  configuration is the /etc/localtime symlink, as that's checked last, and
  tzlocal will return the first configuration found.

- The above change also means that GMT and UTC are no longer seen as synonyms,
  as zoneinfo does not see them as synonyms. This might be controversial,
  but you just have to live with it. Pick one and stay with it. ;-)

4.0.2 (2021-10-26)
------------------

- Improved the error message when you had a conflict including a
  /etc/localtime symlink.

4.0.1 (2021-10-19)
------------------

- A long time bug in Ubuntu docker images seem to not get fixed,
  so I added a workaround.

4.0.1b1 (2021-10-18)
--------------------

- Handle UCT and Zulu as synonyms for UTC, while treating GMT and
  UTC as different.

4.0 (2021-10-18)
----------------

- No changes.

4.0b5 (2021-10-18)
------------------

- Fixed a bug in the Windows DST support.

4.0b4 (2021-10-18)
------------------

- Added support for turning off DST in Windows. That only works in
  whole hour timezones, and honestly, if you need to turn off DST,
  you should just use UTC as a timezone.

4.0b3 (2021-10-08)
------------------

- Returning pytz_deprecation_shim zones to lower the surprise for pytz users.

- The Windows OS environment variable 'TZ' will allow an override for
  setting the timezone. The override timezone will be asserted for
  timezone validity bit not compared against the systems timezone offset.
  This allows for overriding the timezone when running tests.

- Dropped support for Windows 2000, XP and Vista, supports Windows 7, 8 and 10.

4.0b2 (2021-09-26)
------------------

- Big refactor; Implemented get_localzone_name() functions.

- Adding a Windows OS environment variable 'TZ' will allow an override for
  setting the timezone (also see 4.0b3).

4.0b1 (2021-08-21)
------------------

- Now finds and compares all the configs (under Unix-like systems) and
  tells you what files it found and how they conflict. This should make
  it a lot easier to figure out what goes wrong.

3.0 (2021-08-13)
----------------

- Modernized the packaging, moving to setup.cfg etc.

- Handles if the text config files incorrectly is a TZ file. (revanSZ)

3.0b1 (2020-09-21)
------------------

- Dropped Python 2 support
- Switched timezone provider from pytz to zoneinfo (PEP 615)

Log message:
*: bump PKGREVISION for egg.mk users

They now have a tool dependency on py-setuptools instead of a DEPENDS

Log message:
time: Replace RMD160 checksums with BLAKE2s checksums

All checksums have been double-checked against existing RMD160 and
SHA512 hashes

Log message:
time: Remove SHA1 hashes for distfiles

Log message:
py-tzlocal: updated to 2.1

2.1:
- No changes.

2.1b1:
- The is_dst flag is wrong for Europe/Dublin on some Unix releases.
  I changed to another way of determining if DST is in effect or not.
- Added support for Python 3.7 and 3.8. Dropped 3.5 although it still works.

Log message:
py-tzlocal: updated to 2.0.0

2.0.0:

Major differences since 1.5.1
- When no time zone configuration can be find, tzlocal now return UTC.
  This is a major difference from 1.x, where an exception would be raised.
  This change is because Docker images often have no configuration at all,
  and the unix utilities will then default to UTC, so we follow that.
- If tzlocal on Unix finds a timezone name in a /etc config file, then
  tzlocal now verifies that the timezone it fouds has the same offset as
  the local computer is configured with. If it doesn't, something is
  configured incorrectly.
- Get timezone via Termux `getprop` wrapper on Android. It's not officially
  supported because we can't test it, but at least we make an effort.

Minor differences and bug fixes
- Skip comment lines when parsing /etc/timezone.
- Don't load timezone from current directory.
- Now verifies that the config files actually contain something before
  reading them.
- Got rid of a BytesWarning
- Now handles if config file paths exists, but are directories.
- Moved tests out from distributions
- Support wheels
