    Fix compileall.py so that it fails on SyntaxErrors · 12b6457e
    Jeremy Hylton yazdı
    The changes cause compilation failures in any file in the Python
    installation lib directory to cause the install to fail.  It looks
    like compileall.py intended to behave this way, but a change to
    py_compile.py and a separate bug defeated it.
    
    Fixes SF bug #412436
    
    This change affects the test suite, which contains several files that
    contain intentional errors.  The solution is to extend compileall.py
    with the ability to skip compilation of selected files.
    
    NB compileall.py is changed so that compile_dir() returns success only
    if all recursive calls to compile_dir() also check success.

"""Module/script to "compile" all .py files to .pyc (or .pyo) file.

When called as a script with arguments, this compiles the directories
given as arguments recursively; the -l option prevents it from
recursing into directories.

Without arguments, if compiles all modules on sys.path, without
recursing into subdirectories.  (Even though it should do so for
packages -- for now, you'll have to deal with packages separately.)

See module py_compile for details of the actual byte-compilation.
