---help---
This module enables target mode for use by the SCST middle
level drivers. You will also need the SCST middle level
drivers from http://scst.sf.net/.
If unsure whether you really want or need this, say N.

Target driver for LSI/MPT XXX cards
===================================
Version X.X.X, XX XXX 200X
--------------------------
This driver was originally developed by Hu Gang and then is developed by
Erik Habbinga <erikhabbinga@inphase-tech.com>. It is on the early stage
of development.
The current maintainer of this driver is Erik. Please send him all
question related to it (CC: scst-devel@lists.sourceforge.net).
