+# Author          : Herton Ronaldo Krzesinski
+#                   Thanks for Aurélio Marinho Jargas for
+#                   helping me out with sed expressions,
+#                   my first expressions were very slow to

+#                   isn't very simple with line oriented tools
+#                   like grep or sed
+# Created On      : Fri Jul 22 20:25:36 2005
+# Modified On     : Wed Aug 03 14:29:14 2005
+# Purpose         : helper script for rpm scriptlets to del a
+#                   entry filter for software from package into
+#                   syslog (supported sysklogd and syslog-ng).
