+
+Different mount options
+-----------------------
+
+Specifying different mount options in difference config sections is allowed.
+When TEST_FS_MOUNT_OPTS differs in the following section TEST_DEV will be
+remounted with new TEST_FS_MOUNT_OPTS automatically before running the test.
+
+
+Multiple file systems
+---------------------
+
+Having different file systems in different config sections is allowed. When
+FSTYP differs in the following section the FSTYP file system will be created
+automatically before running the test.
+
+Note that if TEST_FS_MOUNT_OPTS, MOUNT_OPTIONS, MKFS_OPTIONS, or FSCK_OPTIONS
+are not directly specified in the section it will be reset to the default for a
+given file system.
+
+You can also force the file system recreation by specifying RECREATE_TEST_DEV.
+
+Run specified section only
+--------------------------
+
+Specifying '-s' argument with section name will run only the section
+specified. The '-s' argument can be specified multiple times to allow multiple
+sections to be run.
+
+The options are still carried between section, that includes the sections
+which are not going to be run. So you can do something like
+
+[ext4]
+TEST_DEV=/dev/sda1
+TEST_DIR=/mnt/test
+SCRATCH_DEV=/dev/sdb1
+SCRATCH_MNT=/mnt/test1
+FSTYP=ext4
+
+[xfs]
+FSTYP=xfs
+
+[btrfs]
+FSTYP=btrfs
+
+
+and run
+
+./check -s xfs -s btrfs
+
+to check xfs and btrfs only. All the devices and mounts are still going to
+be parsed from the section [ext4].
