+-------- Remove this line and what's below it, for reference only. --------
+
+To ensure that your bug report is handled correctly by bugfiler(8),
+you must replace "folder" (on the line above starting with "Index:")
+with one of the following values:
+
+ folder ::= bin | doc | etc | games | ideas | include | lib | local
+ | man | misc | new | sys | ucb | usr.bin | usr.lib
+
+If you're not running 4.3BSD, you should also replace "4.3BSD" on the
+same line with one of the following values.
+
+ version ::= V7 | 2BSD | 4.1BSD | 4.2BSD | 4.3BSD
+
+For example, if your bug concerns the program "/usr/bin/file" and you're
+currently running 4.2BSD, you should replace "folder" with "usr.bin", and
+"4.3BSD" with "4.2BSD". The folder "ideas" is for suggestions.
