Summary: Writes files atomically via rename()

Description:
This module offers atomic file writes via a temporary file created in the
same directory (and therefore, probably the same partition) as the
specified *file*. After data has been written to the temporary file, the
'rename' call is used to replace the target *file*. The module optionally
supports various sanity checks (*min_size*, *CHECKSUM*) that help ensure
the data is written without errors.

Should anything go awry, the module will 'die' or 'croak'. All calls should
be wrapped in eval blocks:

eval {
File::AtomicWrite->write_file(...);
};
if ($@) {
die "uh oh: $@";
}
