When you want to build a program from source and it fails due to missing headers. Auto-apt can search what package would provide the header files.

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);
