+# This code will try to correct the string on the line based on the
+# strings generated for the context if `compconfig[correct]' is set.
+# These corrected strings will be shown in a list and one can
+# cycle through them as in a menucompletion or get the corrected prefix.
+#
+# Supported configuration keys:
+#
+#  approximate_accept
+#    This should be set to a number, specifying the maximum number
+#    of errors that should be accepted. If the string also contains
+#    a `n' or `N', the code will use the numeric argument as the
+#    maximum number of errors if a numeric argument was given. If no
+#    numeric argument was given, the number from the value of this
+#    key will be used. E.g. with `compconf approximate_accept=2n' two
+#    errors will be accepted, but if the user gives another number
+#    with the numeric argument, this will be prefered. Also, with
+#    `compconf approximate_accept=0n', normally no correction will be
+#    tried, but if a numeric argument is given, automatic correction
+#    will be used. On the other hand, if the string contains an `!'
+#    and a `n' or `N', correction is not attempted if a numeric
+#    argument is given. Once the number of errors to accept is
+#    determined, the code will repeatedly try to generate matches by
+#    allowing one error, two errors, and so on. Independent of the
+#    number of errors the user wants to accept, the code will allow
+#    only fewer errors than there are characters in the string from
+#    the line.
+#
+#  approximate_original
+#    This value is used to determine if the original string should
+#    be included in the list (and thus be presented to the user when
+#    cycling through the corrections). If it is set to any non-empty
+#    value, the original string will be offered. If it contains the
+#    sub-string `last', the original string will appear as the last
+#    string when cycling through the corrections, otherwise it will
+#    appear as the first one (so that the command line does not
+#    change immediately). Also, if the value contains the sub-string
+#    `always', the original string will always be included, whereas
+#    normally it is included only if more than one possible
+#    correction was generated.
+#
+#  approximate_prompt
+#    This can be set to a string that should be printed before the
+#    list of corrected strings when cycling through them. This string
+#    may contain the control sequences `%n', `%B', etc. known from
+#    the `-X' option of `compctl'. Also, the sequence `%e' will be
+#    replaced by the number of errors accepted to generate the
+#    corrected strings.
+#
+#  approximate_insert
+#    If this is set to a string starting with `unambig', the code
+#    will try to insert a usable unambiguous string in the command
+#    line instead of always cycling through the corrected strings.
+#    If such a unambiguous string could be found, the original
+#    string is not used, independent of the setting of
+#    `approximate_original'. If no sensible string could be found,
+#    one can cycle through the corrected strings as usual.

+# matches the pattern given as argument after the function name (in this

+# With the `-k' option a function for a special completion keys is

+# of key specifications as accepted by the `bindkey' builtin.

+# whose name is given as the first argument be autoloaded. When defining

+# commands.
+# For deleting definitions, the `-d' option must be given. Without the
