+
+       History (Nils Sjoholm):
+       10.02.1998  First version for Amiga.
+                   Just GetDate and GetTime.
+
+       11.02.1998  Added AmigaToDt and DtToAmiga
+                   Changed GetDate and GetTime to
+                   use AmigaToDt and DtToAmiga.
+
+                   Added DiskSize and DiskFree.
+                   They are using a string as arg
+                   have to try to fix that.
+
+       12.02.1998  Added Fsplit and FExpand.
+                   Cleaned up the unit and removed
+                   stuff that was not used yet.
+
+       13.02.1998  Added CToPas and PasToC and removed
+                   the uses of strings.
+
+       14.02.1998  Removed AmigaToDt and DtToAmiga
+                   from public area.
+                   Added deviceids and devicenames
+                   arrays so now diskfree and disksize
+                   is compatible with dos.
