+Usage: uncompyle [OPTIONS]... [ FILE | DIR]...
+
+Examples:
+  uncompyle      foo.pyc bar.pyc       # uncompyle foo.pyc, bar.pyc to stdout
+  uncompyle -o . foo.pyc bar.pyc       # uncompyle to ./foo.dis and ./bar.dis
+  uncompyle -o /tmp /usr/lib/python1.5 # uncompyle whole library
+
+Options:
+  -o <path>     output decompiled files to this path:
+                if multiple input files are decompiled, the common prefix
+                is stripped from these names and the remainder appended to
+                <path>
+                  uncompyle -o /tmp bla/fasel.pyc bla/foo.pyc
+                    -> /tmp/fasel.dis, /tmp/foo.dis
+                  uncompyle -o /tmp bla/fasel.pyc bar/foo.pyc
+                    -> /tmp/bla/fasel.dis, /tmp/bar/foo.dis
+                  uncompyle -o /tmp /usr/lib/python1.5
+                    -> /tmp/smtplib.dis ... /tmp/lib-tk/FixTk.dis
+  -c <file>     attempts a disassembly after compiling <file>
+  -d            do not print timestamps
+  -p <integer>  use <integer> number of processes
+  -r            recurse directories looking for .pyc and .pyo files
+  --verify      compare generated source with input byte-code
+                (requires -o)
+  --help        show this message
+
+Debugging Options:
+  --showasm   -a  include byte-code                  (disables --verify)
+  --showast   -t  include AST (abstract syntax tree) (disables --verify)
+
+Extensions of generated files:
+  '.dis'             successfully decompiled (and verified if --verify)
+  '.dis_unverified'  successfully decompile but --verify failed
+  '.nodis'           uncompyle failed (contact author for enhancement)
