+Configuration file with sections
+================================
+
+Configuration file with sections is useful for running xfstests on multiple
+file systems, or multiple file system setups in a single run without any
+help of external scripts.
+
+Syntax for defining a section is the following:
+
+[section_name]
+
+Section name should consist of alphanumeric characters and '_'. Anything
+else is forbidden and the section will not be recognised.
+
+Each section in the configuration file should contain options in the format
+
+OPTION=value
+
+'OPTION' must not contain any white space characters. 'value' can contain
+any character you want with one simple limitation - characters ' and " can
+only appear at the start and end of the 'value', however it is not required.
+
+Note that options are carried between sections so the same options does not
+have to be specified in each and every sections. However caution should be
+exercised not to leave unwanted options set from previous sections.
+
+For every section xfstests will run with specified options and will produce
+separate results in the '$RESULT_BASE/$section_name' directory.
+
+Here is an example of config file with sections:
+
+[ext4_4k_block_size]
+TEST_DEV=/dev/sda
+TEST_DIR=/mnt/test
+SCRATCH_DEV=/dev/sdb
+SCRATCH_MNT=/mnt/test1
+MKFS_OPTIONS="-q -F -b4096"
+FSTYP=ext4
+
+[ext4_1k_block_size]
+MKFS_OPTIONS="-q -F -b1024"
+
+[ext4_nojournal]
+MKFS_OPTIONS="-q -F -b4096 -O ^has_journal"
+
+[ext4_discard_ssd]
+MKFS_OPTIONS="-q -F -b4096"
+TEST_DEV=/dev/sdc
+SCRATCH_DEV=/dev/sdd
+MOUNT_OPTIONS="-o discard"
