+=head1 FUNCTIONS
+
+=over
+
+=item B<mailgroup>(I<$default>)
+
+Check if the mailgroup I<$default> exists. Return the checked
+group name or some other random but existing group.
+
+=item B<dynamic_socket>()
+
+Return a dynamically allocated listener socket in the range
+between 1024 and 65534;
+
+=item ($binary, @argv) = B<exim_binary>(I<@argv>)
+
+Find the Exim binary. Consider the first element of I<@argv>
+and remove it from I<@argv>, if it is an executable binary.
+Otherwise search the binary (while honouring C<EXIM_BUILD_SUFFIX>,
+C<../scripts/os-type> and C<../os-arch>) and return the
+the path to the binary and the unmodified I<@argv>.
+
+=item B<flavour>()
+
+Find a hint for the current flavour (Linux distro). It does so by checking
+typical files in the F</etc> directory.
+
+=item B<flavours>()
+
+Return a list of available flavours. It does so by scanning F<log/>, F<stdout/> and
+F<stderr/> for I<flavour> files (extensions after the numerical prefix.
