+# Version 0.7
+
+# NOTE: At present, this script only works for files with C-like comments.
+# NOTE: If you don't specify -p, the script will act on the current working directory.
+# NOTE: If no arguments are specified, the defitions below are in effect.
+
+# TO DO
+#  - Deuglifiy?
+#  - Make source file type agnostic modelines?
+#  - Too many/too few comments?
+#  - Handle top level source directories with whitespace names? (Do they exist?)
+
+# Turn off globbing, helps with SourceFiles
+set -f
+
+# POSIX
+set -o posix
+
+# Change these to taste
