+# This is an Nmap command line parser. It has two main parts:
+#
+# getopt_long_only_extras, which is like getopt_long_only with robust
+# handling of unknown options.
+#
+# NmapOptions, a class representing a set of Nmap options.
+#
+# NmapOptions is the class for external use. NmapOptions.parse parses a list of
+# a command followed by command-line arguments. NmapOptions.render returns a
+# list of of a command followed by arguments. NmapOptions.parse_string and
+# NmapOptions.render_string first split strings into lists, following certain
+# quoting rules.
+#
+# >>> ops = NmapOptions()
+# >>> ops.parse(["nmap", "-v", "--script", "safe", "localhost"])
+# >>> ops.executable
+# 'nmap'
+# >>> ops.target_specs
+# ['localhost']
+# >>> ops["-v"]
+# 1
+# >>> ops["--script"]
+# 'safe'
+#
+# The command line may be modified by accessing member variables:
+#
+# >>> ops.executable = "C:\Program Files\Nmap\nmap.exe"
+# >>> ops["-v"] = 2
+# >>> ops["-oX"] = "output.xml"
+# >>> ops.render()
+# ['C:\\Program Files\\Nmap\\nmap.exe', '-v', '-v', '-oX', 'output.xml',
+# '--script', 'safe', 'localhost']
+# >>> ops.render_string()
+# '"C:\\Program Files\\Nmap\\nmap.exe" -v -v -oX output.xml\
+# --script safe localhost'
+#
+# A primary design consideration was robust handling of unknown options. That
+# gives this code a degree of independence from Nmap's own list of options. If
+# an option is added to Nmap but not added here, that option is treated as an
+# "extra," an uninterpreted string that is inserted verbatim into the option
+# list. Because the unknown option may or may not take an argument, pains are
+# taken to avoid interpreting any option ambiguously.
+#
+# Consider the following case, where -x is an unknown option:
+# nmap -x -e eth0 scanme.nmap.org
+# If -x, whatever it is, does not take an argument, it is equivalent to
+# nmap -e eth0 scanme.nmap.org -x
+# that is, a scan of scanme.nmap.org over interface eth0. But if it does take
+# an argument, its argument is "-e", and the command line is the same as
+# nmap eth0 scanme.nmap.org -x -e
+# which is a scan of the two hosts eth0 and scanme.nmap.org, over the default
+# interface. In either case scanme.nmap.org is a target but the other arguments
+# are ambiguous. To resolve this, once an unknown option is found, all
+# following arguments that can be interpreted ambiguously are removed with it
+# and placed in the extras, with normal option processing resumed only when
+# there is no more ambiguity. This ensures that such options maintain their
+# relative order when rendered again to output. In this example "-x -e eth0"
+# will always appear in that order, and the -e option will be uninterpreted.
+#
+# To add a new option, one should do the following:
+# 1) Add a test case to the NmapOptionsTest::test_options() method for the new
+# option and make sure it initially fails.
+# 2) Add the new option to NmapOptions.SHORT_OPTIONS and/or
+# NmapOptions.LONG_OPTIONS.
+# 3) Add an appropriate case to NmapOptions::handle_result(). This should
+# include a line something like
+# self[opt] = True
+# or, if the option has an argument 'arg':
+# self[opt] = arg
+# 4) Add an appropriate case to NmapOptions::render()
+# This should include a check to make sure the option was set in
+# handle_result:
+# if self[opt]:
+# or, if self[opt] contains arguments
+# if self[opt] is not None:
+# If the check passed, then opt should be added to opt_list.
+# 5) Edit profile_editor.xml to display the new option in the GUI.
+# 6) Depending on the option, one may need to edit
+# get_option_check_auxiliary_widget in OptionBuilder.py.
+# 7) Make sure the test case works now.
