I am looking for a little assistance in seeing if I can parse plus/minus (inclusion/negation) arguments with 'commandline'.

i.e. Argument options like:

• someexecutable -optimize+ -unsafe-
• -optimize[+|-]
• -unsafe[+|-]
• -warnaserror[+|-]

Maybe I am just missing something or I have not had enough coffee, but this one is stumping me.
