and will be used it there is no popt library on your build host, or if
the --with-included-popt option is passed to ./configure.
+If you configure using --enable-maintainer-mode, then rsync will try
+to pop up an xterm on DISPLAY=:0 if it crashes. You might find this
+useful, but it should be turned off for production builds.
HP-UX NOTES
accepts a DESTDIR variable for help in building binary packages.
(Peter Breitenlohner, Greg Louis)
+ * If configured with --enable-maintainer-mode, then on receipt of
+ a fatal signal rsync will try to open an xterm running gdb,
+ similarly to Samba's "panic action" or GNOME's bug-buddy.
