I'm used to the command line parameters handling of CustApp, but none of
my applications are TCustomApp based. Plus CustApp gives no code reuse
regarding command line parameters code. So I refactored the code out of
TCustomApp into an Interface and Class implementing that interface. So
now if I need good parameter list handling I simply mix in Interface
Delegation into any of my applications. This seems to work very well
thus far.

Would this be of interest to Free Pascal? If so, I can refactor the
CustApp code to use the Interface too.

If you wanted to take a look, the code is in the fpg_cmdlineparams.pas
unit in fpGUI. The ICmdLineParams interface and TfpgCmdLineParams class
(ignore the other deprecated class in that unit).
