-Specifies the directory to search for the F<error_table.et> file.
+Specifies the directory to search for the F<error_table.et> file. Specifies
+the directory to search for the prolog file when the B<-h> option is
+given. The B<-p> <I<prefix>> option is a synonym for B<-prefix> <I<prefix>>.
+
+=item B<-h> <I<include>>
+
+Specifies an input file, called a prolog file, and modifies the name of the
+header file generated by B<afs_compile_et>.
+
+When the B<-h> option is given, B<afs_compile_et> will search for a prolog file
+named <I<include>>F<.p.h>. B<afs_compile_et> will search the current working
+directory for the prolog file, unless the B<-p> option is given. If the prolog
+file is found, B<afs_compile_et> will place a verbatim copy of the prolog
+file contents into the generated header file.
+
+When the B<-h> option is given, the name of the header file generated by
+B<afs_compile_et> is <I<include>>F<.h>, instead of <I<error_table>>F<.h>.
+
+The B<-h> option does not affect the source file generated by B<afs_compile_et>.
