Plugin for Composer to require the presence of a binary on the target system

Configuring required system binaries

On every composer install and composer update, a check runs to verify that certain system binaries are available in the PATH. The list of these binaries is maintained in composer.json under extra.required-binaries:

{
    "extra": {
        "required-binaries": ["graphicsmagick", "qpdf"]
    }
}

To add another binary, simply add its name (as it is invoked on the command line) to this array. If one of the listed binaries is missing on the system, Composer aborts with an error message. These binaries are not installed by Composer and must be provided on the system manually (e.g. via the operating system's package manager).
