App::Rsnapshot::CheckGNUcp - check that a binary is GNU cp
my $isgnucp = App::Rsnapshot::CheckGNUcp::isgnucp($binary);
Provides a function to attempt to figure out whether a given binary is GNU cp or not.
This function will be exported if you ask for it thus:
use App::Rsnapshot::CheckGNUcp qw(isgnucp);
Takes a filename (with path) and returns true if it is GNU cp, false otherwise.
This is a heuristic. That means that it can be wrong. Bug reports are most welcome, and should include the output from 'cp --version' as well as, of course, telling me what the bug is.
The check is actually whether 'cp -al blah/foo blah/bar' results in two files with the same inode number.
