+[Q12]	``The `gencat' utility cannot process the input which are
+	  successfully used on my Linux libc based system.  Why?''
+
+[A12] {UD} Unlike the author of the `gencat' program which is distributed
+with Linux libc I have read the underlying standards before writing the
+code.  It is completely compatible with the specification given in
+X/Open Portability Guide.
+
+To ease the transition from the Linux version some of the non-standard
+features are also present in the `gencat' program of GNU libc.  This
+mainly includes the use of symbols for the message number and the automatic
+generation of header files which contain the needed #defines to map the
+symbols to integers.
+
+Here is a simple SED script to convert at least some Linux specific
+catalog files to the XPG4 form:
