+/****************************************************************************
+Try to get the disk space from Veritas disk quotas.
+    David Lee <T.D.Lee@durham.ac.uk> August 1999.
+
+Background assumptions:
+    Potentially under many Operating Systems.  Initially Solaris 2.
+
+    My guess is that Veritas is largely, though not entirely,
+    independent of OS.  So I have separated it out.
+
+    There may be some details.  For example, OS-specific "include" files.
+
+    It is understood that HPUX 10 somehow gets Veritas quotas without
+    any special effort; if so, this routine need not be compiled in.
+        Dirk De Wachter <Dirk.DeWachter@rug.ac.be>
+
+Warning:
+    It is understood that Veritas do not publicly support this ioctl interface.
+    Rather their preference would be for the user (us) to call the native
+    OS and then for the OS itself to call through to the VxFS filesystem.
+    Presumably HPUX 10, see above, does this.
+
+Hints for porting:
+    Add your OS to "IFLIST" below.
+    Get it to compile successfully:
+        Almost certainly "include"s require attention: see SUNOS5.
+    In the main code above, arrange for it to be called: see SUNOS5.
+    Test!
