Option parse

is there a better, or different way to pipe arguments to a program
rather than using optparse? or is that the best and fastest way?

Well, there are more possiblilities:

http://www.ruby-doc.org/stdlib/libdoc/getoptlong/rdoc/index.html

http://www.ruby-doc.org/stdlib/libdoc/yaml/rdoc/index.html

But all depends on what is your meaning of "best". On the question of
speed, I think this is mainly irrelevant. You only read start up options
once.

Check out the OptionParser gem. I find it to be simpler than optparse, though you may differ in your opinion...

i prefer not to parse options, or at least i've written it one final time:

   http://codeforpeople.com/lib/ruby/main/main-0.0.2/samples/a.rb
   http://codeforpeople.com/lib/ruby/main/main-0.0.2/samples/b.rb
   http://codeforpeople.com/lib/ruby/main/main-0.0.2/samples/c.rb
   http://codeforpeople.com/lib/ruby/main/main-0.0.2/samples/d.rb

   gem install main

with main you can abstract all that repetitive stuff into a few declarative statements.

we can deny everything, except that we have the possibility of being better. simply reflect on that.
