+
+This suite of functions retrieves and parses ident information, as stored
+in the commit and tag objects or produced by C<var GIT_type_IDENT> (thus
+C<TYPE> can be either I<author> or I<committer>; case is insignificant).
+
+The C<ident> method retrieves the ident information from C<git-var>
+and either returns it as a scalar string or as an array with the fields parsed.
+Alternatively, it can take a prepared ident string (e.g. from the commit
+object) and just parse it.
+
+C<ident_person> returns the person part of the ident - name and email;
+it can take the same arguments as C<ident> or the array returned by C<ident>.
+
+The synopsis is like:
+
+	my ($name, $email, $time_tz) = ident('author');
+	"$name <$email>" eq ident_person('author');
+	"$name <$email>" eq ident_person($name);
+	$time_tz =~ /^\d+ [+-]\d{4}$/;
+
+Both methods must be called on a repository instance.
