+# This function tries to automatically complete long option names. For 
+# this it invokes the command from the line with the `--help' option
+# and then parses the output to find possible option names. For
+# options that get an argument after a `=', the function also tries to 
+# automatically find out what should be complete as the argument.
+# The possible completions for option-arguments can be described with
+# the arguments to this function. This is done by giving pairs of
+# patterns and actions as consecutive arguments. The actions specify
+# what should be done to complete arguemts of those options that match 
+# the pattern. The action may be a list of words in brackets or in
+# parentheses, separated by spaces. A list in brackets denotes
+# possible values for an optional argument, a list in parentheses
+# gives words to complete for mandatory arguments. If the action does
+# not start with a bracket or parentheses, it should be the name of a
+# command (probably with arguments) that should be invoked to complete 
+# after the equal sign. E.g.:
+#
+#  _long_options '*\*'     '(yes no)' \
+#                '*=FILE*' '_files' \
+#                '*=DIR*'  '_files -/'
+#
+# This makes `yes' and `no' be completed as the argument of options
+# whose description ends in a star, file names for options that
+# contain the substring `=FILE' in the description, and paths for
+# options whose description contains `=DIR'. Note the last two
+# patterns are not needed since this function always completes files
+# for option descriptions containing `=FILE' and paths for option
+# descriptions that contain `=DIR' or `=PATH'. These builtin patterns
+# can be overridden by patterns given as arguments, though.
+#
+# This function also accepts the `-X', `-J', and `-V' options which
+# are given to `compadd'. Finally, it accepts the option `-t'. If this 
+# is given, completion is only done on words starting with two hyphens.

+# This function is called from functions that do matching whenever they

+# It gets the name of the calling function and two names of parameters
+# as arguments. The first one is used in the calling function to build
+# the pattern used for matching possible completions. The content of this
+# parameter on entry to this function is the string taken from the line.
+# Here it parameter should be changed to a pattern that matches words as
+# the match specs currently in use do.
+# In the calling function this pattern may be changed again or used only 
+# in parts. The second parameter whose name is given as the third argument
+# allows to give pattern flags liek `(#l)' that are to be used whenever
+# matching is done.
+#
+# As an example, if you have global match specifications like:
+#
+#  compctl -M 'm:{a-z}={A-Z}' 'm:{a-z}={A-Z} r:|[.-]=* r:|=*'
+#
+# This function would look like:

+#   eval "${3}='(#l)'"
+#   [[ MATCHER -eq 2 ]] && eval "$1='${(P)2:gs/./*./:gs/-/*-/}'"
+#
+# The first line makes sure that matching is done case-insensitive as
+# specified by `m:{a-z}={A-Z}'. The second line replaces dots and hyphens
