:cvar aliases: Other accepted names for this command.
364
:cvar takes_args: List of argument forms, marked with whether they are
365
optional, repeated, etc. Examples::
367
['to_location', 'from_branch?', 'file*']
369
* 'to_location' is required
370
* 'from_branch' is optional
371
* 'file' can be specified 0 or more times

:cvar takes_options: List of options that may be given for this command.
374
These can be either strings, referring to globally-defined options, or
375
option objects. Retrieve through options().

:cvar encoding_type: Command objects will get a 'outf' attribute, which has
381
been setup to properly handle encoding of unicode strings.
382
encoding_type determines what will happen when characters cannot be
385
* strict - abort if we cannot decode
386
* replace - put in a bogus character (typically '?')
387
* exact - do not encode sys.stdout
389
NOTE: by default on Windows, sys.stdout is opened as a text stream,
390
therefore LF line-endings are converted to CRLF. When a command uses
391
encoding_type = 'exact', then sys.stdout is forced to be a binary
392
stream, and line-endings will not mangled.
