=head1 DESCRIPTION
An importer and remover for public-inboxes which takes L<Email::MIME>
-messages as input and stores them in a ssoma repository as
-documented in L<https://ssoma.public-inbox.org/ssoma_repository.txt>,
+messages as input and stores them in a git repository as
+documented in L<https://public-inbox.org/public-inbox-v1-format.txt>,
except it does not allow duplicate Message-IDs.
It requires L<git(1)> and L<git-fast-import(1)> to be installed.
