The AddOption functionality includes help text which will be shown if you use '-h'. However, if you also use Variables help the option text will be lost -- if you use Help(vars.generateHelpText(env)).

There appears to be no clear way to generate the options help text so it can't simply be appended to the variables help text.

The -H option also fails to show the options help text.

Essentially you can't combine options and variables and have a working help text.

Essentially duplicate of #2258

Test SConstruct to reproduce bug:

AddOption(
    "--debugging",
    dest="debugging",
    action="store_true",
    default=False,
    metavar="BDEBUGGING",
    help="Compile with debugging symbols",
)

vars = Variables()
vars.Add(ListVariable("buildmod", "List of modules to build", "none", ["python"]))

env = Environment()
 
# Comment me out for different help outputs
Help(vars.GenerateHelpText(env))

Fixed with commit ef05fbf9b1bf.

Should be released with SCons 2.4.1
