"There are four modes of action:\n"+
"\n"+
"- `list`: will list the scripts installed\n"+
"- `install`: installs the scripts for the modules listed on the command line. The scripts must either be packed in a\n"+
"repository, or found in the current script folders\n"+
"- `uninstall`: uninstalls the scripts for the modules listed on the command line\n"+
"- `pack`: packs the scripts for the modules listed on the command line and publishes them to the specified output repository\n"+
"\n"+
"The list of modules specified can have their versions set, but if missing we will try to find the\n"+
"version from the current source path. If the list of modules is omitted, we will use the list of\n"+
"modules found in the current source path."
