 # Generates a full project for a HeadersTest app.
 # This is a compile-time test checking if all the installed headers can be included individually.
 #
 # Example for KDb:
 # % ./headers_test.sh ~/kde/build/kdb ~/kde/src/kdb KDb kdb .
 #
 # It is assumed that this script is executed from the current build subdirectory.
 # Source dir goes to the app/ subdirectory, build dir goes to the app-build subdirectory.
 # Nothing is cached, both dirs are fully recreated on each run.
