My .bash_profile used on my MacBooko Pro: Includes development tools in PATH. Prepends /usr/local/bin and /usr/local/sbin to PATH, since on Mac OS the default PATH has /usr/bin before /usr/local/bin (for what ever reason). Sets up the prompt and bash completion. Configures man pages to be shown in PDF Viewer.
