As for exec, I am just using it because it makes sense to run the final command in the same process, replacing the wrapper script instead of spawning a new process. It's not strictly necessary.

100% VimL compatibility - we may not support all features of VimL plugins / configuration.

A shell script is a file of executable commands that has been stored in a text file. When the file is run, each command is executed.

I don't know what then, I just remember somehow. Around the same time I install renoise, I also install vim. Then in renoise I go to Help>Show Preferences Folder.... Then I right click on Config.xml, then edit in VIM. Then I /search for showscr or something like that. Change false into true, done. On windows sometimes I'm lazy and I just modify the one shortcut that I use to have --scripting-terminal or something as an argument. Also: if you really do a lot of (re)installs I would advise to back up your Config.xml anyway, just like the KeyBindings.xml, TemplateSong.xrns, etc, it'll save you a lot of time right?

In my opinion one of the key properties of a scripting language is not to be found in the language itself, but rather the tools that are used to deploy it. Traditionally a script in Perl or Python can just be run, without explicitly invoking a complex compilation and linkage script.
