=head1 upload-s3-file.pl
Uploads a single file to an S3 bucket.
This command uploads a file from your Virtualmin system to Amazon's S3
service. The login and password for S3 must be set using the
C<--access-key> and C<--secret-key> flags, unless defaults have been set in
the Virtualmin configuration.
The C<--bucket> flag must be given to specify the bucket to store the file
in, the C<--source> flag to choose the file to upload, and the C<--file>
flag to set the destination filename. The optional C<--rrs> flag can be used
to tell S3 that the file should be stored with reduced redundancy, which
is cheaper but has a lower reliability SLA.
By default, this command will perform a multi-part S3 upload only for files
above 2GB in size. However, you can force multi-part mode with the
C<--multipart> flag. Amazon requires that files above 5GB in size be multi-part
uploaded.
By default each S3 operation will only be tried once. However, you can use
the C<--tries> flag to have Virtualmin re-try failed operations some number
of times.
