The comments are stored directly with the code itself and the IDE is
designed to extract them automatically. The execution environment and the
development environment are the same thing. A shipping system can be purged
of unnecessary information for delivery to the customer but they are
virtually the same, or compiled to machine code if so desired.

Say it was a factory you owned and the person is from some department or a
job agency. Could you even call them your employees? Where is the immediacy?

At the end of the day there is a deeper philosophical issue here. An IDE
user is like a spreadsheet user, he is both a developer and consumer and he
shouldn't have to revert to primitive or external tools to customize or
gain immediate functional insight the very tools and program libraries he
is working with.
