 173   "  THE INTERACTIVE FUNCTIONS PROVIDED BY THE LIBRARY `ogonek'.
 174
 175 If you read this text then you are either looking at the library's
 176 source text or you have called the `ogonek-how' command. In the
 177 latter case you may remove this text using `\\[kill-buffer]'.
 178
 179 The library provides functions for changing the encoding of Polish
 180 diacritic characters, the ones with an `ogonek' below or above them.
 181 The functions come in the following groups.
 182
 183  1. `ogonek-recode-region' and `ogonek-recode-buffer' to change
 184     between one-character encodings, such as `iso-8859-2', `mazovia',
 185     plain `ascii' or `TeX'. As the names suggest you may recode
 186     either the entire current buffer or just a marked region
 187     in it. You may use the functions interactively as commands.
 188     Once you call a command you will be asked about the code
 189     currently used in your text and the target encoding, the one
 190     you want to get. The following example shows a non-interactive
 191     use of the functions in a program. This also illustrates what
 192     type of parameters the functions expect to be called with:
 193
 194       (ogonek-recode-region
 195         (region-beginning) (region-end) from-code-name to-code-name)
 196       (ogonek-recode-buffer from-code-name to-code-name)
 197
 198  2. `ogonek-prefixify-region' and `ogonek-prefixify-buffer' for
 199     introducing prefix notation:
 200
 201       (ogonek-prefixify-region
 202         (region-beginning) (region-end) from-code-name prefix-char)
 203       (ogonek-prefixify-buffer from-code-name prefix-char)
 204
 205  3. `ogonek-deprefixify-region' and `ogonek-deprefixify-buffer' for
 206     removing prefix notation:
 207
 208       (ogonek-deprefixify-region
 209         (region-beginning) (region-end) prefix-char to-code-name)
 210       (ogonek-prefixify-buffer prefix-char to-code-name)
 211
 212  The TAB character used in interactive mode makes `emacs'
 213  display the list of encodings recognized by the library. The list
 214  is stored in the constant `ogonek-name-encoding-alist'.
 215
 216  The `ogonek' functions refer to five variables in which the suggested
 217  answers to dialogue questions are stored. The variables and their
 218  default values are:
 219
 220    ogonek-from-encoding           iso8859-2
 221    ogonek-to-encoding             ascii
 222    ogonek-prefix-char             /
 223    ogonek-prefix-from-encoding    iso8859-2
 224    ogonek-prefix-to-encoding      iso8859-2
 225
 226  The above default values can be changed by placing appropriate settings
 227  in your init file:
 228
 229    (setq ogonek-prefix-char ?/)
 230    (setq ogonek-prefix-to-encoding \"iso8859-2\")
 231
 232  Instead of loading the whole library `ogonek' it may be better
 233  to autoload the needed functions, for example by adding the
 234  following lines to your init file:
 235
 236    (autoload \\='ogonek-how \"ogonek\")
 237    (autoload \\='ogonek-recode-region \"ogonek\")
 238    (autoload \\='ogonek-prefixify-region \"ogonek\")
 239    (autoload \\='ogonek-deprefixify-region \"ogonek\")
 240
 241  The most frequent function calls can be abbreviated and assigned to
 242  keyboard keys. Here are a few practical examples:
 243
 244    (defun deprefixify-iso8859-2-region (start end)
 245      (interactive \"*r\")
 246      (ogonek-deprefixify-region start end ?/ \"iso8859-2\"))
 247    (global-set-key \"\\C-cd\" \\='deprefixify-iso8859-2-region) ; ctrl-c d
 248
 249    (defun mazovia-to-iso8859-2 (start end)
 250      (interactive \"*r\")
 251      (ogonek-recode-region start end \"mazovia\" \"iso8859-2\"))
 252    (global-set-key \"\\C-cr\" \\='mazovia-to-iso8859-2) ; ctrl-c r
 253
 254    (defun prefixify-iso8859-2-region (start end)
 255      (interactive \"*r\")
 256      (ogonek-prefixify-region start end \"iso8859-2\" ?/))
 257    (global-set-key \"\\C-cp\" \\='prefixify-iso8859-2-region) ; ctrl-c p
