language agnostic - What should NOT be under source control?

Question

It would be nice to have a more or less complete list over what files and/or directories that shouldn't (in most cases) be under source control. What do you think should be excluded?

Suggestion so far:

In general

• Config files with sensitive information (passwords, private keys etc.)
• Thumbs.db, .DS_Store and desktop.ini
• Editor backups: *~ (emacs)
• Generated files (for instance DoxyGen output)

C#

• bin*
• obj*
• *.exe

Visual Studio

• *.suo
• *.ncb
• *.user
• *.aps
• *.cachefile
• *.backup
• _UpgradeReport_Files

Java

• *.class

Eclipse

I don't know, and this is what I'm looking for right now :-)

Python

• *.pyc

Temporary files - .*.sw? - *~

Anything that is generated. Binary, bytecode, code/documents generated from XML.

From my commenters, exclude:

• Anything generated by the build, including code documentations (doxygen, javadoc, pydoc, etc.)

But include:

• 3rd party libraries that you don't have the source for OR don't build.

FWIW, at my work for a very large project, we have the following under ClearCase:

• All original code
• Qt source AND built debug/release
• (Terribly outdated) specs

We do not have built modules for our software. A complete binary is distributed every couple weeks with the latest updates.
