+# absolute paths: @skip_parse_files_abs
+# file names: @skip_parse_files_any

+# The use of @skip_xxx_xxx_any causes files to be skipped where ever they occur.
+# For example adding 'fd' to @skip_walk_dirs_any causes the fd/ directory to be
+# skipped for all PID sub-directories of /proc
+#
+# The same thing can be achieved by passing command line options to --dont-walk
+# and --dont-parse. If absolute paths are supplied to these options they are
+# appended to the @skip_xxx_xxx_abs arrays. If file names are supplied to these
+# options, they are appended to the @skip_xxx_xxx_any arrays.
