This question already has an answer here:
I don't know what Scout is, but here's the story, I dual booted my Windows XP last week, installing Linux Mint 12 and I wanted today to download Eclipse IDE.
On the download page, I see this
Developing Scout applications is supported by this Scout Developers Package.
Anyway, the question is, if Scout is not a popular language then why would Eclipse make an IDE for it?
If it is popular, then why doesn't Stack Overflow have a tag for it?
If you search for
scout in the tag list, you'll see
bugzscout which is an entirely different thing.
