The only problem with this method of plugins....

The resulting IDE is still monolithic... let me explain:

If you load/install a 3rd party plugin for your ide, that is missing an 
external include, or has bugs...

Then prg2.exw, or whatever you call it, will crash. And the user will not 
necissarily know what has happened, and unless the plugin installer-loader 
is separate from the main ide, there is not a user-level way to unload it.

I know that the trickery that you have described will work, as long as all 
the plugins are perfectly working. However, for a more robust ide, the idea 
of dll's and an API is much better, as it allows for some kind of "This 
plugin could not load" message, and for the IDE to continue functioning.

Unless of course, Rob allowed an "include(sequence file)" function, that 
returned either 0 for success, or an error code showing how the include 
failed... It's ok Rob, maybe for Eu2.6

;oP
