Description

Currently if you subclass the org.apache.camel.spring.Main class, then the command line options of Main are available, but using -h produces a list of options headed by:

"Apache Camel Runner takes the following options"

It would be nice to be able to change this in the sub-class. Overriding showOptions() is not satisfactory and the option list is stored a a private field with no getter, meaning the list of options cannot be generated.

I have provided a patch for one possible solution, that allows for just the header part of showOptions() to be overriden.
(it also moves the generation of the information line into the Option class instead of the showOptions method itself to allow for further customisation, if required.
