[Insight-developers] Should the itkTclAppInit function be split out of itkTclAppInit.cxx?

[Kent Williams]

So if, for the sake of argument, you wanted to roll your own Tcl/Tk/Itk 
etc Tcl interpreter executable.  The way you have to do this currently 
is copy the itkTclAppInit.cxx file and customize the main() function to 
add your other initializations.

It seems to me a better 'plug and play' system would be to move 
itkTclAppInit into its own source file, separate from the main() for 
itkwish.  That way, you can reference that function in your own program, 
without copying and modifying ITK source.

Or is there a better way? Can ITK be loaded into a 'vanilla' wish or 
tkwish with 'package require'?
