Could not finde anything in the documentation.

hou.HDADefinition.save(release_hda_path, template_node, compile_contents=True, black_box=True)
Also, you can check the file in “Side Effects Software\Houdini 17.5.397\toolkit\include\HOM\HOM_HDADefinition.h”
by the line of 118.
SWIGOUT(%kwargs save;) virtual void save( const std::string &file_name, HOM_Node *template_node = NULL, HOM_HDAOptions *options = NULL, bool compile_contents = false, bool black_box = false, bool create_backup = true) = 0;

within this context, what is a template node?
I've been able to successfully save a regular HDA with "save" but trying to save a blackbox HDA has gotten me stumped.
Here is what I've been doing:
```
# trivial subnet
geo = hou.node("/obj").createNode("geo")
subnet = geo.createNode("subnet", "license")
sphere_node = subnet.createNode("sphere")
output_node = subnet.createNode("output")
output_node.setInput(0, sphere_node)
subnet.layoutChildren()
# create HDA node and HDADefinition
hda_node = subnet.createDigitalAsset(name="test", compress_contents=True, version="1.0", save_as_embedded=False, ignore_external_references=True, change_node_type=True, create_backup=False)
hda_def = hda_node.type().definition()
hda_def.save("/tmp/test.hda") # works
hda_def.save("/tmp/blackbox.hda", black_box=True) # creates regular HDA because no "template_node"
hda_def.save("/tmp/blackbox.hda", template_node=subnet, black_box=True) # crashes
```
