## Installation / désinstallation ##

install : $(TARGET)
	@$(CP) $(TARGET) $(INSTALL_DIR)
	@cd $(INSTALL_DIR) ; chown root:root $(TARGET) ; chmod 755 $(TARGET)

install-static : $(TARGET).static
	@$(CP) $(TARGET).static $(INSTALL_DIR)
	@cd $(INSTALL_DIR) ; chown root:root $(TARGET).static ; chmod 755 $(TARGET).static

uninstall :
	@$(RM) $(INSTALL_DIR)/{$(TARGET),$(TARGET).static}


## Nettoyage ##

clean :
	@$(RM) -fv *~ *.o *.d

purge : clean
	@$(RM) -fv $(TARGET) $(TARGET).static
