• Configs, e.g. many dotfiles.
• Tools for daily use.

The simplest way is to run ./deploy.sh. It will symlink those utilities to where they belong. If the destination already exists and isn't a symlink from us, deploy.sh will do nothing but to prompt you.
Be sure to read the output and manually process the conflicts. Or, some of my utilities may not work due to lack of dependency.

You can use ./deploy.sh | grep -i warning -B 3 to get a list of conflict rules.

Since my deploy.sh uses some commands in Linux way, those options may not be available (or correct) on a MAC. I'm highly accustomized to the Linux commands so I have to get them back:

• Install HomeBrew. Remember to brew doctor and brew update before you proceed.
• Install Linux core-utils: brew install coreutils
• To not conflict MAC's commands, those Linux commands will be prefixed with a "g". You can find them in either /usr/local/bin/guname or ../Cellar/coreutils/8.21/bin (assume coreutils 8.21). You should link them to a place in your $PATH using the name without "g" prefix.

After the preparation, everything is just as Linux. deploy.sh it!
