Unused #includes in C++ source lead to unwanted dependencies and slower compile and link timings.

IncludeChecker finds most of these unused #includes using a simple heuristic: if you include a file, you need to use one or more symbols from it. If that's not the case, IncludeChecker will mark the #include as unused.

IncludeChecker is very customizable to be able to run as an automated task where it will fail as soon as an unused #include is detected.

Because of the simple heuristic it will not find all unused #includes, but it will find most of them.

Features:

• Scanning of single files or complete subdirectories.
• Troublesome includes can be ignored.
• Global type prefixes and suffixes can be configured.
• Easy to setup to run as a build check.
