Built-in console archive manager

UnifiedArchive is distributed with a unified console program to manipulate popular archive formats. This script is stored in vendor/bin/cam.

It supports all formats that UnifiedArchive does and can be used to manipulate archives without other software. To check your configuration and check formats support launch it with -f flag in console:

$ php vendor/bin/cam -f
