there. This package overrides the implementation of these methods, not
the semantics.
+The mode of operation of these routines depend on the VMS features that
+are controlled by the DECC features C<DECC$FILENAME_REPORT_UNIX> and
+C<DECC$EFS_CHARSET>.
+
+Perl needs to be at least at 5.10 for these feature settings to work.
+Use of them on older perl versions on VMS will result in unpredictable
+operations.
+
+The default and traditional mode of these routines have been to expect VMS
+syntax on input and to return VMS syntax on output, even when Unix syntax was
+given on input.
+
+The default and traditional mode is also incompatible with the VMS
+C<EFS>, Extended File system character set, and with running Perl scripts
+under <GNV>, Gnu is not VMS, an optional Unix like runtime environment on VMS.
+
+If the C<DECC$EFS_CHARSET> feature is enabled, These routines will now accept
+either VMS or UNIX syntax. If the input parameters are clearly VMS syntax,
+the return value will be in VMS syntax. If the input parameters are clearly
+in Unix syntax, the output will be in Unix syntax.
+
+This corresponds to the way that the VMS C library routines have always
+handled filenames, and what a programmer who has not specifically read this
+pod before would also expect.
+
+If the C<DECC$FILENAME_REPORT_UNIX> feature is enabled, then if the output
+syntax can not be determined from the input syntax, the output syntax will be
+UNIX. If the feature is not enabled, VMS output will be the default.
