+
+Command-Line Usage: |soi-textconv|
+===================================
+
+.. program:: |soi-textconv|
+
+Terse syntax command to convert |objects.inv| to |stdout|. Extends
+:code:`git diff`. Comparing against partially binary
+|objects.inv| versions, produces useful results.
+
+Rather than *These two binary files differ*
+
+Unlike |soi|, |soi-textconv| coding style is ``adapt to survive``.
+Regardless of what's thrown at it, does what it can.
+
+Difference
+
+- when an inventory file is piped in from |stdin|, specifying "-" is optional
+
+- checks |stdin| even before parsing cli arguments
+
+----
+
+**Usage**
+
+.. command-output:: sphobjinv-textconv --help
+    :ellipsis: 4
+
+.. versionadded:: 2.4.0
+
+.. seealso::
+
+   Step by step configuration, usage, and code samples
+
+   :doc:`git_diff`
+
+**Positional Arguments**
+
+.. option:: infile
+
+    Path (or URL, if :option:`--url` is specified) to file to be converted.
+
+    If passed as ``-``, |soi-textconv| will attempt import of a plaintext or JSON
+    inventory from |stdin| (incompatible with :option:`--url`).
+
+**Flags**
+
+.. option:: -h, --help
+
+    Display help message and exit.
+
+.. option:: -u, --url
+
+    Treat :option:`infile` as a URL for download. Cannot be used when
+    :option:`infile` is passed as ``-``.
+
+.. option:: -e, --expand
+
+    Expand any abbreviations in `uri` or `dispname` fields before writing to output;
+    see :ref:`here <syntax_shorthand>`.
+
+**Examples**
+
+Remote URL
+
+.. code-block:: shell
+
+   export URL="https://github.com/bskinn/sphobjinv/raw/main/tests/resource/objects_attrs.inv"
