Syntax: #{shell_command} prefix|use parameters...

### Examples for command prefixes:
#{shell_command} prefix
- shows command prefixes, when a "ki command" is executed ki looks for the command with all prefix combinations
#{shell_command} prefix version package
- sets two command prefixes, looks for "command", "version-command" and "package-command"
#{shell_command} prefix + foo
- adds one command prefix to existing ones, looks for "command", "version-command", "package-command", "foo-command"
#{shell_command} prefix - package foo
- removes two command prefixes from list
#{shell_command} prefix -c
- clears command prefix list

### Examples for default script loading:
#{shell_command} use
- shows list of automatically loading scripts. when ki starts up, it looks for all defined versions and loads all files tagged with "ki"
#{shell_command} use ki/http ki/ftp/123:ki-extra
- scripts are loaded from two different version. ki/http uses latest available version and files tagged with "ki", ki/ftp uses specific version and files tagged with "ki-extra"
#{shell_command} use + ki/scp
- adds one more script package version
#{shell_command} use - ki/scp ki/ftp/123:ki-extra
- removes two configurations
#{shell_command} use -c
- clear use list

### Examples for default Ruby file requiring:
#{shell_command} require
#{shell_command} require hooves/default
#{shell_command} require + hooves/default
#{shell_command} require - hooves/default
#{shell_command} require -c
