+         Caldera OpenDOS Machine Readable Source Kit (M.R.S) 7.01
+         ========================================================
+
+
+1.0 SOURCE CODE LICENSE AGREEMENT
+
+    Please familiarise your self with the Caldera Source Code
+    License agreement in the file LICENSE.TXT before doing anything
+    with this M.R.S. kit.
+
+2.0 BUILDING THE COMPONENTS
+
+
+2.1 INSTALLING SOURCE FROM CD MEDIA
+
+    Copy the SOURCE directory from the CD to your hard disk. Use
+    XCOPY /S to preserve subdirectories.
+
+    Use the ATTRIB command to reset the READ-ONLY attribute on the
+    files copied to the hard disk prior to building, since all files
+    copied from the CD-ROM will have the READ-ONLY bit set.
+
+
+2.2 INSTALLING SOURCE FROM A ZIP FILE
+    
+    PKUNZIP the source archive file to hard disk using the -d switch 
+    to preserve the subdirectory structure.
+
+
+2.3 BUILDING THE MRS KIT
+
+    The Caldera OpenDOS MRS kit contains the following components:
+
+                 IBMBIO, IBMDOS and COMMAND
+
+    These components are accompanied with batch files (MAKE.BAT)
+    that enable them to be built.  These batch files are to be
+    found at the root of each component directory.
+
+    TOOLS
+    =====
+    In order to build these components we have provided some of
+    the "in house" tools that were developed to aid the process.
+    The remainder of the tools have been omitted as you need to
+    obtain the required licences for them.
+
+    The following third party tools were used to build the 
+    executables. Other versions of these tools may work but have
+    not been tested.
+
+    Tool			Component
+    ====			=========
+    Watcom C v7.0		COMMAND
+    Borland C v2.0		COMMAND
+    Microsoft MASM v4.0 	IBMBIO, COMMAND
+    Microsoft Link v5.10	IBMBIO, COMMAND
+    Microsoft Lib v3.0		IBMBIO
+
+    IBMBIO
+    ======
+    To build IBMBIO.COM run the MAKE.BAT found in the root of the
+    IBMBIO\ directory.  The MAKE.BAT file sets environment variables
+    that point to the local tools directory and to the Third Party
+    tools required.  The Third party tools directory is set to 
+    C:\TOOLS but this can be changed by editing the MAKE.BAT file 
+    if required.
+
+    When this component has built all built files are placed in the
+    BIN\ directory under the component.
+
+
+    IBMDOS
+    ======
+    To build IBMDOS.COM run the MAKE.BAT found in the root of the
+    IBMDOS\ directory.  The MAKE.BAT file sets environment variables
+    that point to the local tools directory and to the Third party tools
+    required.  The Third party tools directory is set to C:\TOOLS 
+    but this can be changed by editing the MAKE.BAT file if required.
+
+    When this component has built all built files are placed in the
+    BIN\ directory under the component.
+
+
+    COMMAND
+    =======
+    To build COMMAND.COM run the MAKE.BAT found in the root of the
+    COMMAND\ directory.  The MAKE.BAT file sets environment variables
+    that point to the local tools directory and to the Third party 
+    tools required.  The Third party tools directory is set to 
+    C:\TOOLS but this can be changed by editing the MAKE.BAT file 
+    if required.
+
+    When this component has built all built files are placed in the
+    BIN\ directory under the component.
+
+    For this component we use the WATCOM optimising compiler, which
+    greatly reduces the size of COMMAND.COM when built.  For this
+    reason it is highly likely that the COMMAND.COM built on your
+    local machine will differ from the shipped version of COMMAND.COM.
+
+    To gain better optimisation you will need a large TPA. This is best
+    achieved by installing OpenDOS 7.01 setup to map Video memory into
+    TPA.
+
+    In days past this component used to be built with the standard
+    Borland compilers (v2.0) and if required can be modified to do so.
