-------------------------------------
-
-CONSTANT:
-    ``CONFIGURE_APPLICATION_NEEDS_LIBBLOCK``
-
-DATA TYPE:
-    Boolean feature macro.
-
-RANGE:
-    Defined or undefined.
-
-DEFAULT VALUE:
-    This is not defined by default.
-
-DESCRIPTION:
-    Provides a Block Device Cache configuration.
-
-NOTES:
-    Each option of the Block Device Cache configuration can be explicitly set
-    by the user with the configuration options below.  The Block Device Cache
-    is used for example by the RFS and DOSFS file systems.

-
-RANGE:
-    Positive.
-
-DEFAULT VALUE:
-    The default value is 32768 bytes.
-
-DESCRIPTION:
-    Size of the cache memory in bytes.
-
-NOTES:
-    None.

-    A value of 0 disables the read-ahead task (default).  The read-ahead task
-    will issue speculative read transfers if a sequential access pattern is
-    detected.  This can improve the performance on some systems.
