Constants
KERNEL_EXIT_SUCCESS = 
true
 

Kernel::exit takes a boolean but defines no constants to describe what it means; very bad form. This constant equates to the 'success' boolean value.
KERNEL_EXIT_FAILURE = 
false
 

Kernel::exit takes a boolean but defines no constants to describe what it means; very bad form. This constant equates to the 'failed' boolean value.
NAME_REGEX = 
/^[a-zA-Z01-9_-]{2,30}$/
 

Regular expression describing allowed names of services (A-Z, a-z, 0-9, underscore or hyphen; between 2 and 30 characters).
Instance Public methods

Run the hoodoo command implementation. Command line options are taken from the Ruby ARGV constant.
