   1 """Module/script to "compile" all .py files to .pyc (or .pyo) file.
   2
   3 When called as a script with arguments, this compiles the directories
   4 given as arguments recursively; the -l option prevents it from
   5 recursing into directories.
   6
   7 Without arguments, if compiles all modules on sys.path, without
   8 recursing into subdirectories.  (Even though it should do so for
   9 packages -- for now, you'll have to deal with packages separately.)

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