Option Syntax
=============

   Since Wget uses GNU getopts to process its arguments, every option
has a short form and a long form.  Long options are more convenient to
remember, but take time to type.  You may freely mix different option
styles, or specify options after the command-line arguments.  Thus you
may write:

     wget -r --tries=10 http://fly.srk.fer.hr/ -o log

   The space between the option accepting an argument and the argument
may be omitted.  Instead `-o log' you can write `-olog'.

   You may put several options that do not require arguments together,
like:

     wget -drc URL

   This is a complete equivalent of:

     wget -d -r -c URL

   Since the options can be specified after the arguments, you may
terminate them with `--'.  So the following will try to download URL
`-x', reporting failure to `log':

     wget -o log -- -x

   The options that accept comma-separated lists all respect the
convention that specifying an empty list clears its value.  This can be
useful to clear the `.wgetrc' settings.  For instance, if your `.wgetrc'
sets `exclude_directories' to `/cgi-bin', the following example will
first reset it, and then set it to exclude `/~nobody' and `/~somebody'.
You can also clear the lists in `.wgetrc' (Note: Wgetrc Syntax).

     wget -X '' -X /~nobody,/~somebody
