Thanx Tony, Your OptionHowTo tutorial was very good. And I started thinking about contributing only after reading it. With every opensource project I want to start working, I dont find how to begin. Your tutorial helped alot.
but I thing you need to add more details, Instead of just telling how to do it, Give an example of implementing something very basic. that will drive more contributers I guess. I want to implement a batch download feature. Format: wget -batch 01-10 http://rahulprasad.com/pics/img[*].jpg this will add http://rahulprasad.com/pics/img01.jpg to http://rahulprasad.com/pics/img10.jpg to the queue. Plz tell me where show I add if(opt.batch) { // Loop // Add to queue. } Also, Please tell me the function used to add to queue. Or refer me to code where *add to queue* is implemented Regards Rahul Prasad --------------------------------------------------------- Web: www.rahulprasad.com 2010/10/14 Tony Lewis <[email protected]> > Rahul Prasad wrote: > > > I cant understand the flow of control.
