+# ABSTRACT: Wget wrapper to retry harder
+# PODNAME:
+
+=head1 SYNOPSIS
+
+Use like you would use B<wget>:
+
+ % wget-retry -c -t0 https://example.com/url1 ...
+
+
+=head1 DESCRIPTION
+
+By default, B<wget> doesn't retry harder; only upon disconnection in the middle
+of downloading (with C<-t>/C<--tries>, e.g. C<-t 0>) and on connection refused
+(with C<--retry-connrefused>) but not on other network failures, e.g. DNS
+resolution failure (which can happen sometimes).
+
+This wrapper runs B<wget> then checks its exit code. If exit code indicates
+network failure (4) it will re-run wget.
+
+The number of tries is unlimited, or from the C<-t> (<--tries>) option. The
+number of seconds to wait before each try is 10 seconds or from the
+C<--waitretry> option.
+
+
+=head1 OPTIONS
+
+=head2 --help
+
+Shortcuts: -h, -?.
+
+=head2 --version
+
+
+=head1 ENVIRONMENT
+
+=head2 WGET_RETRY_EXIT_STATUSES
+
+A comma-separated list of exit statuses to retry. For example, C<1,3,4,5,6,7,8>
+means generic error (1), file I/O error (3), network failure (4), SSL
+verification failure (5), username/password authentication failure (6), protocol
+errors (7), as well as error response from server (8) will make wget-retry rerun
+wget. The default is 1,3,4,5,6,7,8. For more details on wget exit statuses, see
+the wget's manpage.
+
+=head2 WGET_RETRY_WGET_CMD
+
+String. Wget command to use. Defaults to C<wget>. Can be used to chain several
+wrappers together.
+
+

+
