What is the mkdict command and what does it do? (It came in distro but has no man page or help)

When using tab completion for mkdir I found a binary existing called mkdict. But I can’t find a man page or other details. A Google search only yields info on a python library with this name, but I don’t think this command can be that. What is it?

I am running Oracle Linux 8 in a VM, without GUI (just cli). Here is some results of commands I tried to find info:

Location:

$ which mkdict
/usr/sbin/mkdict

Trying to find something:

$whatis mkdict
mkdict: nothing appropriate.

$man mkdict
No manual entry for mkdict

$help mkdict
-bash: help: no help topics match 'mkdict'

$mkdict --help
-d, --decrompressdecompress

$dnf info mkdict*
Error: No matching Packages to list 

If I try to run it, then nothing really seems to happen. Perhaps it is waiting for input. The terminal just sits trying to run it until I do a Ctrl-Break.

A Google search for mkdict + linux only gives results on a Python package of the same name, at least in the results I reviewed. But it seems unlikely this is that package, which is has apparently little downloads from PyPI.

What is mkdict and what does it do or is for?
