ctrl/modopts.d directory
The modopts.d sub-directory off of the ctrl directory contains module-specific configuration files (in .ini format).
These files are merged with the contents of the ctrl/modopts.ini file via this line in that file:
!include modopts.d/*.ini
Adding .ini files to this directory is virtually the same as adding the contents of those files into the modopts.ini file.
Note: The modopts.d/*.ini files must still contain their module-specific section heading (e.g. [modname]).
