+
+ Reform string library.
+
+ * output.c (init_default_drivers): Update call to
+ configure_driver() to new interface.
+ (get_option_token) Use a modifiable substring in interface instead
+ of a separate position parameter. Use ss_get_*() functions.
+ (configure_driver) Take and work with substrings.
+ (configure_driver_line) Update call to configure_driver() to new
+ interface.
+ (outp_get_paper_size) Use substrings.
+
+ * output.h (struct outp_class): Change open_driver interface to
+ use substring. Update all implementations.
+
+ * table.c (text_format): Change to return substring.
+ (tab_title) Use xvasprintf().
+
+ * table.h (struct tab_table): Change title member to char *.

+
+ * table.c: Removed redundant extern declaration.

+Sun May 14 14:03:56 2006 Ben Pfaff <blp@gnu.org>
+
+ * output.c (outp_eject_page): Always make sure that a page is open
+ upon return.

+
+ * postscript.c: (ps_chart_finalise) Fix format of %%EndDocument
+ comment, which screwed up gv's idea of where one page ended and
+ the next one began. Thanks to John Darrington for pointing out
+ the bug.

+
+ Start reforming error message support. In this phase, we get rid
+ of "installation errors" and change all uses of msg() in the
+ output drivers to uses of error() or error_at_line().
+
+ * Removed all inclusion of <libpspp/message.h> in this directory.
+
+ * output.c: Changed all uses of msg() to error() or
+ error_at_line().
+ (outp_read_devices) Maintain line number in int variable instead
+ of "struct file_locator".
+ (tokener) Renamed get_option_token(), rewritten, changed interface.
+ (outp_parse_options) Change `options' argument to type const
+ struct string *. Rewritten.
+ (configure_driver) Passes a struct string * to ->open_driver()
+ instead of char *.
+ (outp_get_paper_size) Maintain line number in int variable instead
+ of "struct file_locator". Removed stupid cache.
+
+ * output.h: (struct outp_class) Change `open_driver' function to
+ take const struct string * instead of const char *. Updated all
+ implementations.

Rewrite a lot of the output drivers and infrastructure.
