Preprocessor Statements (originally called "IDE Flags") are things the Compiler takes care of before doing the actual compilation.
- attach other files with #attach("")
- copy files to the output directory with #copy("")
- copy folders to the output directory with #copyFolder("")
(NOTE: If the path given in #copy or #copyFolder is not rooted it will use the /Packages directory as a root. #copy and #copyFolder also support using the current working directory by using the $CWD placeholder like this #copy("$CWD/path/to/file"))
