I know unrecognized options are put in ARGV (I don't recall if
everything on the command-line is), so you can do things like "if
--debug-auto-load in [ modules.peek : ARGV ] ...." (that's an example
from my setup). It doesn't require any modification to

There's also an example of an argument with a value in bootstrap.jam:
"local build-system = [ MATCH --build-system=(.*) : $(ARGV) ] ;"

Hope this helps!
