+"""jc - JSON Convert `asciitable-m` parser
+
+This parser converts ASCII and Unicode text tables with multi-line rows.
+Tables must have some sort of separator line between rows.
+
+For example:
+
+    ╒══════════╤═════════╤════════╕
+    │ foo      │ bar baz │ fiz    │
+    │          │         │ buz    │
+    ╞══════════╪═════════╪════════╡
+    │ good day │ 12345   │        │
+    │ mate     │         │        │
+    ├──────────┼─────────┼────────┤
+    │ hi there │ abc def │ 3.14   │
+    │          │         │        │
+    ╘══════════╧═════════╧════════╛
+
+Usage (cli):
+
+    $ cat table.txt | jc --asciitable-m
+
+Usage (module):
+
+    import jc
+    result = jc.parse('asciitable_m', asciitable-string)
+
+Schema:
+
+    [
+      {
+        "asciitable-m":     string,
+        "bar":     boolean,
+        "baz":     integer
+      }
+    ]
+
+Examples:
+
+    $ asciitable-m | jc --asciitable-m -p
+    []
+
+    $ asciitable-m | jc --asciitable-m -p -r
+    []
