+
+``app/pmdinfogen``
+
+
+``pmdinfogen`` scans an object (.o) file for various well known symbol names.  These
+well known symbol names are defined by various macros and used to export
+important information about hardware support and usage for pmd files.  For
+instance the macro:
+
+.. code-block:: c
+
+    PMD_REGISTER_DRIVER(drv, name)
+
+
+Creates the following symbol:
+
+.. code-block:: c
+
+   static char this_pmd_name0[] __attribute__((used)) = "<name>";
+
+
+Which pmdinfogen scans for.  Using this information other relevant bits of data
+can be exported from the object file and used to produce a hardware support
+description, that pmdinfogen then encodes into a json formatted string in the
+following format:
+
+.. code-block:: C
+
+   static char <name_pmd_string>="PMD_INFO_STRING=\"{'name' : '<name>', ...}\"";
+
+
+These strings can then be searched for by external tools to determine the
+hardware support of a given library or application.
