When run argc --argc-compgen bash '' mycmd '' without setting the argcfile(the fourth argument), argc will automatically search for the script file at $ARGC_COMPLETIONS_PATH.

This can reduce the difficulty of using argc as a completion engine.

Users now can create a my-completions-dir directory and then place argc-based completion scripts within that directory.
Use the following code to autoload the completion scripts in the directory.

export ARGC_COMPLETIONS_PATH=my-completions-dir
eval <(ls -1 my-completions-dir | sed -n 's/\.sh$//p' | xargs argc --argc-completions bash)
