# Some important, global variables in tmake:
#   cpp_ext	C++ extension added to moc output (.cpp)
#   obj_ext	Object file extension (.o on Unix, .obj otherwise)
#   moc_aware	Will scan for files containing Qt signals/slots
#   moc_pre	Moc prefix for generated moc file: x.h -> moc_x.cpp
#   moc_ext	Moc extension for generated moc file: x.cpp -> x.moc
#   moc_cmd	The moc command in your makefile, $(MOC)
#   uic_decl	Uic extension for generated declaration file: x.ui -> x.h
#   uic_impl	Uic extension for generated implementation file: x.ui -> x.cpp
#   uic_cmd	The uic command in your makefile, $(UIC)
#   uic_decl_path	The path where the generated decl files from uic files are created, $(INTERFACE_DECL_PATH)
#   linebreak	Line break character (\)
#   dir_sep	Directory separator (/ on Unix, \ on Windows)
#   is_unix	Autodetected. If not Unix, assume Windows (Win32).
#
# If you need to customize any of these settings, do it before
# calling StdInit() in the template file.
