+  File    | M_OPS.PAS
+  Desc    | Compiler options include file.  This file is included in all
+            units within MDL.  This file should create some basic
+            definitions relating to the target operating system as well as
+            include compiler specific compiler options (if ported to work
+            with multiple compilers).  This is also where some program
+            specific options will be found (such as the ability to compile
+            in DEBUG or RELEASE mode, etc).
+
+  Created | August 22, 2002
+  Notes   | Sets up the following compiler directives:
+
+            COMPILERS:
+              $FPC : Set if compiler is Free Pascal
+
+            OPERATING SYSTEMS:
+              $UNIX    : Set if target OS is unix style
+              $LINUX   : Set if target OS is linux
+              $WINDOWS : Set if target OS is windows
+              $DARWIN  : Set if target OS is Mac OSX
+
+            FILE SYSTEMS:
+              $FS_SENSITIVE : Set if target file system is case sensitive
+              $FS_IGNORE    : Set if target file system is not case sensitive
