Handle.CompileSourceHigh-level compilation functions.
gen_obj indicates whether we should generate object files when compiling source files. The default behaviour is not to generate them.
compile force mp compiles module path mp, forcing recompilation of up-to-date files if force is true.
compile_file force fname looks for a package configuration file for fname and compiles fname, forcing recompilation of up-to-date files if force is true. It is the main compiling function. It is called from the main program exclusively.
The functions provided in this module perform the same computations as the ones defined earlier, but restore the console state and the library mappings when they have finished. An optional library mapping or console state can be passed as argument to change the settings.
