// This hook should be placed in the 'after_prepare' hook folder.

// The hook relies on a JSON file located at '<project_root>/resources/.build.json' to track the build number.
// build.json content:
// {"build: 1}

// Add 'BUILDNR' to the version number in the '<project_root>/config.xml' file.

// this plugin replaces arbitrary text in arbitrary files

// Look for the string CONFIGURE HERE for areas that need configuration
