"""
Usage: decompyle [OPTIONS]... [ FILE | DIR]...
Examples:
decompyle foo.pyc bar.pyc # decompyle foo.pyc, bar.pyc to stdout
decompyle -o . foo.pyc bar.pyc # decompyle to ./foo.dis and ./bar.dis
decompyle -o /tmp /usr/lib/python1.5 # decompyle whole library
Options:
-o <path> output decompyled files to this path:
if multiple input files are decompyled, the common prefix
is stripped from these names and the remainder appended to
<path>
decompyle -o /tmp bla/fasel.pyc bla/foo.pyc
-> /tmp/fasel.dis, /tmp/foo.dis
decompyle -o /tmp bla/fasel.pyc bar/foo.pyc
-> /tmp/bla/fasel.dis, /tmp/bar/foo.dis
decompyle -o /tmp /usr/lib/python1.5
-> /tmp/smtplib.dis ... /tmp/lib-tk/FixTk.dis
--verify compare generated source with input byte-code
(requires -o)
--help show this message
Debugging Options:
--showasm include byte-code (disables --verify)
--showast include AST (abstract syntax tree) (disables --verify)
Extensions of generated files:
'.dis' successfully decompyled (and verified if --verify)
'.dis_unverified' successfully decompyled but --verify failed
'.nodis' decompyle failed (contact author for enhancement)
