+#!/bin/sh
+
+# This is an example shell script that can be used as a wrapper for a
+# msdos.fsck (called by the generic fsck frontend).
+#
+# This script is the second version. It uses a new feature of libdmsdos,
+# the built-in direct translation that can access a CVF even if the host
+# filesystem is not mounted. This is now the preferred way.
+#
+# The script accepts a standard fsck command line and decides upon the
+# the raw filesystem data whether it is a CVF or not. If it is a CVF then
+# dmsdosfsck is invoked.
+#
+# The case when it is not a CVF but an uncompressed msdos partition is a bit
+# more complex. First, dosfsck is invoked to check that dos partition. Then
+# the script scans its root directory for CVFs. If there are CVFs it tries 
+# to check them, too, by calling dmsdosfsck on them. If the -r option is 
+# present in the fsck command line, some questions are asked.
+#
+# Note that this script needs a helper program that finds out whether a 
+# file is a CVF or not. If you have added the file(1) magics for CVFs to
+# /etc/magic (see the dmsdos installation instructions) you can use a
+# combination of file and grep (for example) for that purpose. I think this
+# is a standard way. If you still prefer the older method (by calling the
+# helper program cvftest) just compile cvftest ('make cvftest') and change 
+# one lines below (I've commented out the cvftest call and placed a
+# file command in the next line).
