liballegro-physfs5.2 binary package in Ubuntu Focal arm64

 This package provides the physfs addon for the Allegro 5 library. This
 addon provides an interface to the PhysicsFS library, allowing you to
 mount virtual file-systems (e.g., archives) and access files as if they
 were physically on the file-system.
 .
 Allegro is a cross-platform library intended for use in computer games
 and other types of multimedia programming. Allegro 5 is the latest major
 revision of the library, designed to take advantage of modern hardware
 (e.g. hardware acceleration using 3D cards) and operating systems.
 Although it is not backwards compatible with earlier versions, it still
 occupies the same niche and retains a familiar style.
