+#Subject: [bash] Universal command options completion?
+#
+#
+#In the recent versions of bash (after 2.04) programmable
+#completion is available. A useful completion function
+#is , for a particular command, to enumerate all flags
+#that can be used in the command. Now, most GNU unix
+#commands have so-called 'long options' for example:
+#
+#ls --color=always --no-group --size
+#
+#and these are all listed when you issue a '--help' flag.
+#So the idea is to use that, then parse the output of the
+#'--help' and reinject this to compgen. The basis of the
+#following 'universal' completion funtion was the _configure_func'
+#written by Ian McDonnald (or is it Chet Ramey ?)
+#A dedicated function will always be better, but this is quite
+#convenient. I chose to use 'long options' because they are
+#easy to parse and explicit too (it's the point I guess...)
+#Lots of room for improvement !
