Revamped, to match py_compile.py:
- added docstrings - support option to specify a different purported directory name - reindented with 4 spaces

+"""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.
