Basically for an addon, import as a module, call the modules register method to enable.
The folder your addon is in is the module name, eg
mesh_stairs/
__init__.py
operators/
__init__.py
foo.py
bar.py
The operators you have in the operators folder already have a register and unregister method. Can from ./operators import foo and in register call foo.register() (as answered by @RJG while I was dawdling along)
Dynamically loading each module in operators folder.
Here is a method I played around with for bat_tools to manage a number of "addons" into one. Enabling / disabling addons for workspaces has prompted somewhat of a rethink.
Pretty generic. Using __all__ and globals. Could load any list or dict etc instead.
