__DATA__

=head1 COMMANDS

=over 4

=item B<buckets>

s3cl_ae buckets

List all buckets for this account.

=item B<mkbucket>

s3cl_ae mkbucket --bucket sombucketname [--jurisdiction [EU|US]]

Create a new bucket, optionally specifying what jurisdiction
it should be created in.

=item B<ls>

s3cl_ae ls <bucket>:[prefix]

List contents of a bucket, the optional B<prefix> can be partial, in which
case all keys matching this as the start of the key name will be returned.
If no B<prefix> is supplied all keys of the bucket will be returned.

=item B<cp>

s3cl_ae cp <bucket>:<key> target_file

s3cl_ae cp <bucket>:<key> target_directory

Copy a single key from the bucket to the target file, or into
the target_directory.

=item B<sync>

s3cl_ae sync <bucket>:[prefix] target_dir

Downloads all files matching the prefix into a directory structure
replicating that of the prefix and all 'sub-directories'. It will
download ALL files - even if already on your local disk:

http://www.amazon.com/gp/browse.html?node=16427261

  #  Data transfer "in" and "out" refers to transfer into and out
  #  of Amazon S3.  Data transferred between Amazon EC2 and
  #  Amazon S3, is free of charge (i.e., $0.00 per GB), except
  #  data transferred between Amazon EC2 and Amazon S3-Europe,
  #  which will be charged at regular rates.

=item B<sync_up>

s3cl_ae sync_up [--acl_short=public-read] /path/ <bucket>:[prefix]

Upload all the files below /path/ to S3, with an optional
prefix at the start of the key name. The existing S3 files and
meta data are fetched from S3 and the md5 (etag) is compaired to
what is on the local disk, files are not upload if the content has
not changed.

Use --acl_short to set access control, options from
L<Net::Amazon::S3::Bucket#set_acl> this is only applied when the
file is uploaded.

Each files content-type is worked out using L<MIME::Types>,
if this does not match 'text/plain' is used for ASCII text files,
otherwise a warning is issued and the file is NOT uploaded.

Currently this does NOT remove old files from S3, and if there is
any change to a file then the entire file will be reuploaded.

=item B<rm>

s3cl_ae rm <bucket>:<key>

Remove a key(file) from the bucket, removing a non-existent file
is not classed as an error. Once removed the key (file) can not
be restored - so use with care!
