This repository contains the platform-specific Adblock Plus source code for Chrome, Opera and Safari. It can be used to build Adblock Plus for these platforms, generic Adblock Plus code will be extracted from other repositories automatically (see dependencies file). This will create a build with a name in the form adblockpluschrome-1.2.3.nnnn.crx or adblockplussafari-1.2.3.nnnn.safariextz. Note that you don't need an existing signing key for Chrome or Opera, a new key will be created automatically if the file doesn't exist. Safari on the other hand always requires a valid developer certificate, you need to get one in the Apple Developer Center first. adblockplussafari.pem should contain the private key for your developer certificate, the developer certificate itself as well as all the certificates it was signed with (Apple's root certificate and intermediate certificates) in PEM format - in that order.
