-"""reindent [-d][-r][-v] [ path ... ]
-
--d (--dryrun) Dry run. Analyze, but don't make any changes to, files.
--r (--recurse) Recurse. Search for all .py files in subdirectories too.
--n (--nobackup) No backup. Does not make a ".bak" file before reindenting.
--v (--verbose) Verbose. Print informative msgs; else no output.
--h (--help) Help. Print this usage information and exit.
-
-Change Python (.py) files to use 4-space indents and no hard tab characters.
-Also trim excess spaces and tabs from ends of lines, and remove empty lines
-at the end of files. Also ensure the last line ends with a newline.
-
-If no paths are given on the command line, reindent operates as a filter,
-reading a single source file from standard input and writing the transformed
-source to standard output. In this case, the -d, -r and -v flags are
-ignored.
-
-You can pass one or more file and/or directory paths. When a directory
-path, all .py files within the directory will be examined, and, if the -r
-option is given, likewise recursively for subdirectories.
-
-If output is not to standard output, reindent overwrites files in place,
-renaming the originals with a .bak extension. If it finds nothing to
-change, the file is left alone. If reindent does change a file, the changed
-file is a fixed-point for future runs (i.e., running reindent on the
-resulting .py file won't change it again).
-
-The hard part of reindenting is figuring out what to do with comment
-lines. So long as the input files get a clean bill of health from
-tabnanny.py, reindent should do a good job.
-
-The backup file is a copy of the one that is being reindented. The ".bak"
-file is generated with shutil.copy(), but some corner cases regarding
-user/group and permissions could leave the backup file more readable that
-you'd prefer. You can always use the --nobackup option to prevent this.
