Static installation -------------------> Dump the script to a global completion file and restart your shell:
%command.full_name% {$shell} | sudo tee {$completionFile}> Or dump the script to a local file and source it:
%command.full_name% {$shell} > completion.sh>
# source the file whenever you use the project>
source completion.sh>
# or add this line at the end of your "{$rcFile}" file:>
source /path/to/completion.sh>

"{$rcFile}">):
