I intend to orphan the python-project-generator-definitions package.

This package currently sits in the Debian Python team and is part of the yotta
build system for the firmware-microbit-micropython package.

https://tracker.debian.org/pkg/python-project-generator-definitions

The package description is:
  This package provides target and MCU definitions for use with the `progen`
  tool (package: python3-project-generator)
  .
  The definitions provided in this package are used to set proper data for
  embedded tools supported by `progen`. New definitions can be created using
  the `progendef` helper script included in this package.
  .
  This package installs the library and `progendef` helper script for Python 3.

Dear submitter,

as the package python-project-generator-definitions has just been removed from the Debian archive
unstable we hereby close the associated bug reports.  We are sorry
that we couldn't deal with your issue properly.

For details on the removal, please see https://bugs.debian.org/1143961

The version of this package that was in Debian prior to this removal
can still be found using https://snapshot.debian.org/.

Please note that the changes have been done on the master archive and
will not propagate to any mirrors until the next dinstall run at the
earliest.

This message was generated automatically; if you believe that there is
a problem with it please contact the archive administrators by mailing
