+# check_disk.pl <host> <share> <user> <pass> [warn] [critical] [port]
+#
+# Nagios host script to get the disk usage from a SMB share
+#
+# Changes and Modifications
+# =========================
+# 7-Aug-1999 - Michael Anthon
+#  Created from check_disk.pl script provided with netsaint_statd (basically
+#  cause I was too lazy (or is that smart?) to write it from scratch)
+# 8-Aug-1999 - Michael Anthon
+#  Modified [warn] and [critical] parameters to accept format of nnn[M|G] to
+#  allow setting of limits in MBytes or GBytes.  Percentage settings for large
+#  drives is a pain in the butt
