[Boost-users] Boost build help

Hi, I just downloaded the IOStreams library, soon to be included in Boost. I needt to install it, so that all the includes will reside wherever they should. I have bjam, but I must be doing something wrong. I'm at the tired, frustrated stage where the documentation is too cryptic. Could someone please explain how I use bjam? The docs say bjam -sTOOLS=gcc my_target. What is "my_target"? Tried teh path to the Jamfile, got an error saying no suitable files can be found...please help, I'm really having a bad day here :( Eyal.
