Suggestion: an automated test to confirm that PhysFS links and works

[v1993]

SDL2_image has an amazing test suite that checks loaders. While it would be great to have that for PhysFS (i.e. have a set of archives with identical content that are compared against reference directory), something simple like

#include <stdio.h>
#include <stdlib.h>

#define PHYSFS_DEPRECATED
#include "physfs.h"

int main(int argc, char **argv) {
    if (!PHYSFS_init(argv[0])) {
        printf("PHYSFS_init() failed!\n  reason: %s.\n", PHYSFS_getLastError());
        return 1;
    }

    printf("PhysFS initialized\n");

    if (!PHYSFS_deinit()) {
        printf("PHYSFS_deinit() failed!\n  reason: %s.\n", PHYSFS_getLastError());
        return 1;
    }

    printf("PhysFS deinitialized\n");
    return 0;
}

would still be fine to confirm that program using PhysFS links and loads.
