ToDo

The output of grep -R PATH_MAX auto-apt-0.3.22/* is a bit long. It contains files that have been patched using #define PATH_MAX XYZ.
Here is the only file of interest:

pkgcdb/pkgtab.c:    char buf[PATH_MAX];
pkgcdb/pkgtab.c:    assert(p - pkg < PATH_MAX);
pkgcdb/pkgtab.c:    static char buf[PATH_MAX];
pkgcdb/pkgtab.c:    assert(len < PATH_MAX);

Reading from stdin using the get_line() function as explained in the porting guide.
