Question about creating RPMs.

Hello folks.

This is the first time I am doing anything like this.

Lets say I have few scripts that I want to create an RPM out of them.

Does the RPM process it self gives instructions on where the scripts will be installed? For example, if I want the file script.sh in /root/bin is that instruction part of the RPM build process?

Also if script.sh needs for example "gcc" to be installed is that something that I need to put instructions in the RPM to resolve or will it be part of the actual script?

I am not clear how the whole thing works.
