InterIMAP depends on the following Perl modules:

  - Config::Tiny
  - DBI
  - DBD::SQLite
  - Getopt::Long (core module)
  - MIME::Base64 (core module) if authentication is required
  - IO::Select (core module)
  - IO::Socket::INET (core module) for 'type=imap'
  - IO::Socket::SSL for 'type=imaps' (or 'type=imap' and 'STARTTLS=YES')
  - List::Util (core module)
  - POSIX (core module)
  - Socket (core module)
  - Time::HiRes (core module) if 'logfile' is set

On Debian GNU/Linux systems, these modules can be installed with the
following command:

  apt-get install libconfig-tiny-perl libdbi-perl libdbd-sqlite3-perl libio-socket-ssl-perl

However Debian GNU/Linux users can also use gbp(1) from git-buildpackage
to build their own package:

  $ git checkout debian
  $ AUTO_DEBSIGN=no gbp buildpackage

Alternatively, for the development version:

  $ git checkout debian
  $ git merge master
  $ AUTO_DEBSIGN=no gbp buildpackage --git-force-create --git-upstream-tree=BRANCH
