Remember that things like ~ and $HOME are unique to the shells you're
using.  These features are non-portable to OS platforms like
Microsoft.  You should look at the vendor-supplied libraries.  If
you're using GNAT, you can use the routine supplied in GNAT.IO_Aux.
Although I hasten to add that you may still have to explicitly expand
the shell symbol.

Good luck!
