The best place to submit patches is to [EMAIL PROTECTED]
Discussions can also happen there, too. Please submit patches against
relatively recent development code, as opposed to the latest release
(which happened ~two years ago), as otherwise the work involved in
bringing it up-to-date may be a disincentive to include it. :)
Information on obtaining the latest development version of Wget is at

As to whether or not it will be included in mainline Wget, that depends
on the answer to your question, "does this seem like something others of
you could use?" I, personally, wouldn't find it very useful (I rarely
use even --limit-rate), so I'd be interested in knowing who would. I
suspect that it may well be the case that most folks who have need of
- --limit-rate will find your version handy, but I want to hear from
them. :)

Also, I'd like a little more understanding about what the use case is:
is it just to use N% less bandwidth than you seem to have available, so
that other connections you may open won't be taxed as much?

A couple notes off the bat: I'd prefer --limit-percent to --limit-pct,
as apparently more recent naming conventions seem to prefer
unabbreviated terms to abbreviated ones. And, I would desire a wgetrc
command to complement the long option version. Don't break your back
working these things into your patch, though: let's first see what
you've got and whether folks want it (lest you waste effort for nothing).
