+Dependencies for Imager
+============================
+
+This information is only relevant for maintainers of Debian packages
+compiled against Imager.
+
+These packages need to depend on the perl-imagerapi-* virtual package
+provided by libimager-perl.
+To generate this dependency please do one of the following:
+
+- debhelper using dh:
+
+Use the "perl_imager" addon and ensure ${perl:Depends} is used in debian/control.
+This requires a build-dependency on libimager-perl (>= 0.93+dfsg-2).
+
+The debian/rules file might look as follows:
+
+ #!/usr/bin/make -f
+ %:
+ dh $@ --with perl_imager
+
+- old-style debhelper:
+
+Run dh_perl_imager after dh_perl and ensure ${perl:Depends} is used in
+debian/control. This requires a build dependency on libdbi-perl (>= 0.93+dfsg-2).
+
+- packages not using debhelper:
+
+Include /usr/share/libdbi-perl/perl-imagerapi.make in debian rules and use
+PERL_IMAGERAPI_DEPENDS. This requires a build-dependency on
+libdbi-perl (>= 0.93+dfsg-2).
+
+See http://bugs.debian.org/693003 for a discussion why this dependency is
+required.

+
+dh_perl_imager - add dependencies required for Imager modules
+
+=head1 SYNOPSIS
+
+B<dh_perl_imager> [S<I<debhelper options>>]
+
+=head1 DESCRIPTION
+
+dh_perl_imager is a debhelper program that is responsible for adding a dependency
+on perl-imagerapi-* to the ${perl:Depends} substitution variable.
+Such a dependency is required for packages that are B<compiled> against Imager;
+do I<not> use this for packages that only B<use> the Imager module.
+
+A debhelper addon is also provided. This makes it possible to just use
+
+ #!/usr/bin/make -f
+ %:
+ dh $@ --with perl_imager
+
+for F<debian/rules>.
