+# usage: ls -1 | ./batch.pl [-o] <# ds to add>
+#
+# -o will let you overwrite your rrds. i don't recommend using this
+# switch the first time you run this program. If something
+# gets messed up, the original xml files will be in the xml
+# directory and you can run 'rrdtool restore' on all of them
+# uncomment the commented out lines below to make this work.
+#
+# also, you can change the name of the directory the XML is
+# getting dumped to, where your rrdtool binary is located,
+# and where add_ds.pl is located. the variables are listed
+# below.
+#
+# This script could theoretically take fully-qualified pathnames
+# as input from STDIN rather than the output from ls -1.
