	-flag true

Command line flag syntax:
-flag
-flag=x
-flag x
-flag x // non-boolean flags only
One or two minus signs may be used; they are equivalent.
The last form is not permitted for boolean flags because the
meaning of the command
cmd -x *
will change if there is a file called 0, false, etc. You must
use the -flag=false form to turn off a boolean flag.
Flag parsing stops just before the first non-flag argument
("-" is a non-flag argument) or after the terminator "--".
