Summary

Find and optionally remove unneeded includes in C or C++ sourcefiles.

deheader analyzes C and C++ files to determine which header inclusions can be removed while still allowing them to compile. This may result in substantial improvements in compilation time, especially on large C++ projects; it also sometimes exposes dependencies and cohesions of which developers were unaware.
