description='''This command lets you run the /bin/ls shell command from

within lldb. This code is designed to demonstrate the best principles that
|
|
should be used when creating a new LLDB command through python.
|
|
Creating the options in a separate function allows the parser to be
|
|
created without running the command. The usage string is generated by the
|
|
optparse module and can be used to populate the ls.__doc__ documentation
|
|
string in the command interpreter function prior to registering the
|
|
command with LLDB. The allows the output of "ls --help" to exactly match
|
|
the output of "help ls" when both commands are run from within LLDB.
