    ``storescu [options] addr port dcmfile``

Description
===========
The ``storescu`` application implements a *Service Class User* (SCU) for
the *Storage Service Class* [#]_. It requests an association with a peer
Application Entity on IP address ``addr`` and ``port`` and, once an
Association is established, requests the transfer of the Storage SOP Instance
in ``dcmfile``.

The following simple example shows what happens when it is succesfully run on
a Storage SCP:
::

    user@host: storescu 127.0.0.1 11112 path/to/file
    user@host:

When attempting to use the Storage Service for a unsupported SOP Class:
::

    user@host: storescu 127.0.0.1 11112 path/to/file
    E: No Acceptable Presentation Contexts
    user@host:

More information is available with the ``-d`` flag:
::

    user@host: storescu 127.0.0.1 11112 path/to/file -d
    D: $storescu.py v0.1.3

Options
=======
Logging
-------
    ``-q    --quiet``
              quiet mode, prints no warnings or errors
    ``-v    --verbose``
              verbose mode, prints processing details
    ``-d    --debug``
              debug mode, prints debugging information
    ``-ll   --log-level [l]evel (str)``
              One of ['critical', 'error', 'warning', 'info', 'debug'], prints
              logging messages with corresponding level or higher
    ``-lc   --log-config [f]ilename (str)``
              use python logging config [#]_ file f for the logger

Application Entity Titles
-------------------------
    ``-aet  --calling-aet [a]etitle (str)``
              set the local AE title (default: ECHOSCU)
    ``-aec  --called-aet [a]etitle (str)``
              set the called AE title for the peer AE (default: ANY-SCP)

Association Negotiation Debugging
---------------------------------
    ``-pts  --propose-ts [n]umber (int)``
              propose n transfer syntaxes (1-3)

Miscellaneous DICOM
-------------------
    ``-to   --timeout [s]econds (int)``
              timeout for connection requests (default: unlimited)
    ``-ta   --acse-timeout [s]econds (int)``
              timeout for ACSE messages (default: 30)
    ``-td   --dimse-timeout [s]econds (int)``
              timeout for DIMSE messages (default: unlimited)
    ``-pdu  --max-pdu [n]umber of bytes (int)``
              set maximum receive PDU bytes to n bytes (default: 16384)
    ``--repeat [n]umber (int)``
        repeat echo n times
    ``--abort``
        abort association instead of releasing it


DICOM Conformance
=================
The storescu application supports the following SOP Class as an SCU:

+------------------+------------------------+
| UID              | SOP Class              |
+==================+========================+
|1.2.840.10008.1.1 | Verification SOP Class |
+------------------+------------------------+

Unless the ``--propose-ts`` option is used, the storescu application will only
propose the *Little Endian Implicit VR Transfer Syntax* (UID 1.2.840.10008.1.2).
The supported Transfer Syntaxes [#]_ are:

+--------------------+---------------------------+
| UID                | Transfer Syntax           |
+====================+===========================+
|1.2.840.10008.1.2   | Little Endian Implicit VR |
+--------------------+---------------------------+
|1.2.840.10008.1.2.1 | Little Endian Explicit VR |
+--------------------+---------------------------+
|1.2.840.10008.1.2.2 | Big Endian Explicit VR    |
+--------------------+---------------------------+
