+lrzip now supports stdout without requiring the '-o -' option. It detects when
+output is being redirected without a filename and will automatically output to
+stdout so you can do:
+ lrunzip patch-2.6.38.4.lrz | patch -p1
+Apple builds will not have errors on compressing files >2GB in size which
+broke with 0.600.
+lrztar will properly support -o, -O and -S.
+lrzip.conf file now supports encryption.
