1 | """Module/script to byte-compile all .py files to .pyc (or .pyo) files.\r |
| 2 | \r | |
| 3 | When called as a script with arguments, this compiles the directories\r | |
| 4 | given as arguments recursively; the -l option prevents it from\r | |
| 5 | recursing into directories.\r | |
| 6 | \r | |
| 7 | Without arguments, if compiles all modules on sys.path, without\r | |
| 8 | recursing into subdirectories. (Even though it should do so for\r | |
| 9 | packages -- for now, you'll have to deal with packages separately.)\r | |
| 10 | \r | |
