+
+Autocompleter.Base handles all the autocompletion functionality
+that's independent of the data source for autocompletion. This
+includes drawing the autocompletion menu, observing keyboard
+and mouse events, and similar.
+
+Specific autocompleters need to provide, at the very least,
+a getUpdatedChoices function that will be invoked every time
+the text inside the monitored textbox changes. This method
+should get the text for which to provide autocompletion by
+invoking this.getToken(), NOT by directly accessing
+this.element.value. This is to allow incremental tokenized
+autocompletion. Specific auto-completion logic (AJAX, etc)
+belongs in getUpdatedChoices.
+
+Tokenized incremental autocompletion is enabled automatically
+when an autocompleter is instantiated with the 'tokens' option
+in the options parameter, e.g.:
+new Ajax.Autocompleter('id','upd', '/url/', { tokens: ',' });
+will incrementally autocomplete with a comma as the token.
+Additionally, ',' in the above example can be replaced with
+a token array, e.g. { tokens: [',', '\n'] } which
+enables autocompletion on multiple tokens. This is most
+useful when one of the tokens is \n (a newline), as it
+allows smart autocompletion after linebreaks.

+
+The local array autocompleter. Used when you'd prefer to
+inject an array of autocompletion options into the page, rather
+than sending out Ajax queries, which can be quite slow sometimes.
+
+The constructor takes four parameters. The first two are, as usual,
+the id of the monitored textbox, and id of the autocompletion menu.
+The third is the array you want to autocomplete from, and the fourth
+is the options block.
+
+Extra local autocompletion options:
+- choices - How many autocompletion choices to offer
+
+- partialSearch - If false, the autocompleter will match entered
+                                       text only at the beginning of strings in the
+                                       autocomplete array. Defaults to true, which will
+                                       match text at the beginning of any *word* in the
+                                       strings in the autocomplete array. If you want to
+                                       search anywhere in the string, additionally set
+                                       the option fullSearch to true (default: off).
+
+- fullSsearch - Search anywhere in autocomplete array strings.
+
+- partialChars - How many characters to enter before triggering
+                                    a partial match (unlike minChars, which defines
+                                    how many characters are required to do any match
+                                    at all). Defaults to 2.
+
+- ignoreCase - Whether to ignore case when autocompleting.
+                                Defaults to true.
+
+It's possible to pass in a custom function as the 'selector'
+option, if you prefer to write your own autocompletion logic.
+In that case, the other options above will not apply unless
+you support them.
