-	A version of the getopt library for use with wide character strings. 
-
-	This is simply the gnu getopt library, but converted for use with
-	wchar_t instead of char. This is not usually useful since the argv
-	array is always defined to be of type char**, but in fish, all
-	internal commands use wide characters and hence this library is
-	useful.
-
-	If you want to use this version of getopt in your program,
-	download the fish sourcecode, available at <a
-	href='http://ridiculousfish.com/shell/'>the fish homepage</a>. Extract
-	the sourcode, copy wgetopt.c and wgetopt.h into your program
-	directory, include wgetopt.h in your program, and use all the
-	regular getopt functions, prefixing every function, global
-	variable and structure with a 'w', and use only wide character
-	strings. There are no other functional changes in this version of
-	getopt besides using wide character strings.
-
-	For examples of how to use wgetopt, see the fish builtin
-	functions, many of which are defined in builtin.c.
