My department, and I assume many others, have an unusual year end problem: they haven't consumed all their budget. If they don't spend it all, then next year the budget will be reduced.
We've recommended numerous small pieces of software, but they've been rejected as "too inexpensive - we need to buy software development tools that cost thousands of dollars per seat!"
- What software development tools (or kind of software development tools) are on your 'wish list' - ie, you can't justify the cost, but you would be able to put to good use if you had them.
- I'm particularly interested in those tools that are stratospheric in terms of cost - you would never be able to justify them for any given project, but can be extraordinarily useful for most development work.
In my case I'd be targeting C code for high reliability use, and .NET tools for in-house use, but please contribute tools for all areas of software development.
One tool per answer, please don't duplicate, and explain what the tool does, what applications/platforms/languages/frameworks/etc it applies to.
