* src/bufferparams.C (readLanguage): use the new language map
* src/intl.C (InitKeyMapper): use the new language map
* src/lyx_gui.C (create_forms): use the new language map
* src/language.[Ch]: New files. Used for holding the information
about each language. Now! Use this new language map enhance it and
make it really usable for our needs.
2000-03-09 Dekel Tsur <dekel@math.tau.ac.il>
* screen.C (ShowCursor): Removed duplicate code.
(ShowManualCursor): Support for 3 cursor shapes: Bar (default),
L (LTR text in RTL document), and reversed-L (RTL text in LTR document)
* src/text.C (NextBreakPoint,Fill): Moved declaration of left_margin

text correctly (change the glyphs of the letter according to the

* src/buffer.C
* src/paragraph.C
* src/lyxrc.h
* src/lyxrc.C Added lyxrc command {language_command_begin,
language_command_end,language_command_ltr,language_command_rtl,
language_package} which allows the use of either arabtex or Omega
for Arabic
* src/lyx_gui.C (init)
* src/lyxrc.h
* src/lyxrc.C Added lyxrc command screen_font_encoding_menu. Allows
to use encoding for menu fonts which is different than the encoding
for screen fonts
* src/buffer.C (makeLaTeXFile): If params.language = "default",
do not load the babel package.
To write an English document with Hebrew/Arabic, change the document
language to "english".
