  24 ;;
  25 ;; This mode is designed to edit many similar varieties of Conf/Ini files and
  26 ;; Java properties.  It started out from Aurélien Tisné's ini-mode.
  27 ;; `conf-space-keywords' were inspired by Robert Fitzgerald's any-ini-mode.

 330   "Mode for Unix and Windows Conf files and Java properties.
 331 Most conf files know only three kinds of constructs: parameter
 332 assignments optionally grouped into sections and comments.  Yet
 333 there is a great range of variation in the exact syntax of conf
 334 files.  See below for various wrapper commands that set up the
 335 details for some of the most widespread variants.
 336
 337 This mode sets up font locking, outline, imenu and it provides
 338 alignment support through `conf-align-assignments'.  If strings
 339 come out wrong, try `conf-quote-normal'.
 340
 341 Some files allow continuation lines, either with a backslash at
 342 the end of line, or by indenting the next line (further).  These
 343 constructs cannot currently be recognized.
 344
 345 Because of this great variety of nuances, which are often not
 346 even clearly specified, please don't expect it to get every file
 347 quite right.  Patches that clearly identify some special case,
 348 without breaking the general ones, are welcome.
 349
 350 If instead you start this mode with the generic `conf-mode'
 351 command, it will parse the buffer.  It will generally well
 352 identify the first four cases listed below.  If the buffer
 353 doesn't have enough contents to decide, this is identical to
 354 `conf-windows-mode' on Windows, elsewhere to `conf-unix-mode'.
 355 See also `conf-space-mode', `conf-colon-mode', `conf-javaprop-mode',
 356 `conf-ppd-mode' and `conf-xdefaults-mode'.
