dirs_exist_ok dictates whether to raise an exception in case dst or any
missing parent directory already exists.
If exception(s) occur, an Error is raised with a list of reasons.
If the optional symlinks flag is true, symbolic links in the
source tree result in symbolic links in the destination tree; if
it is false, the contents of the files pointed to by symbolic
links are copied. If the file pointed by the symlink doesn't
exist, an exception will be added in the list of errors raised in
an Error exception at the end of the copy process.
You can set the optional ignore_dangling_symlinks flag to true if you
want to silence this exception. Notice that this has no effect on
platforms that don't support os.symlink.
The optional ignore argument is a callable. If given, it
is called with the `src` parameter, which is the directory
being visited by copytree(), and `names` which is the list of
`src` contents, as returned by os.listdir():
callable(src, names) -> ignored_names
Since copytree() is called recursively, the callable will be
called once for each directory that is copied. It returns a
list of names relative to the `src` directory that should
not be copied.
The optional copy_function argument is a callable that will be used
to copy each file. It will be called with the source path and the
destination path as arguments. By default, copy2() is used, but any
function that supports the same signature (like copy()) can be used.

If ignore_errors is set, errors are ignored; otherwise, if onerror
is set, it is called to handle the error with arguments (func,
path, exc_info) where func is platform and implementation dependent;
path is the argument to that function that caused it to fail; and
exc_info is a tuple returned by sys.exc_info(). If ignore_errors
is false and onerror is None, an exception is raised.

similar to the Unix "mv" command. Return the file or directory's
destination.
If the destination is a directory or a symlink to a directory, the source
is moved inside the directory. The destination path must not already
exist.
If the destination already exists but is not a directory, it may be
overwritten depending on os.rename() semantics.
If the destination is on our current filesystem, then rename() is used.
Otherwise, src is copied to the destination and then removed. Symlinks are
recreated under the new name if os.rename() fails because of cross
filesystem renames.
The optional `copy_function` argument is a callable that will be used
to copy the source or it will be delegated to `copytree`.
By default, copy2() is used, but any function that supports the same
signature (like copy()) can be used.
A lot more could be done here... A look at a mv.c shows a lot of
the issues this implementation glosses over.

'base_name' is the name of the file to create, minus any format-specific
extension; 'format' is the archive format: one of "zip", "tar", "gztar",
"bztar", or "xztar". Or any other registered format.
'root_dir' is a directory that will be the root directory of the
archive; ie. we typically chdir into 'root_dir' before creating the
archive. 'base_dir' is the directory where we start archiving from;
ie. 'base_dir' will be the common prefix of all files and
directories in the archive. 'root_dir' and 'base_dir' both default
to the current directory. Returns the name of the archive file.
'owner' and 'group' are used when creating a tar archive. By default,
uses the current owner and group.

If it's unable to handle an archive, it needs to raise a ReadError
exception.

`filename` is the name of the archive.
`extract_dir` is the name of the target directory, where the archive
is unpacked. If not provided, the current working directory is used.
`format` is the archive format: one of "zip", "tar", "gztar", "bztar",
or "xztar". Or any other registered format. If not provided,
unpack_archive will use the filename extension and see if an unpacker
was registered for that extension.
In case none is found, a ValueError is raised.
If `filter` is given, it is passed to the underlying
extraction function.

}t� ||f�S )a Get the size of the terminal window.
For each of the two dimensions, the environment variable, COLUMNS
and LINES respectively, is checked. If the variable is defined and
the value is a positive integer, it is used.
When COLUMNS or LINES is not defined, which is the common case,
the terminal connected to sys.__stdout__ is queried
by invoking os.get_terminal_size.
If the terminal size cannot be successfully queried, either because
the system doesn't support querying, or because we are not
connected to a terminal, the value given in fallback parameter
is used. Fallback defaults to (80, 24) which is the default
size used by many terminal emulators.
The value returned is a named tuple of type os.terminal_size.

a3 Given a command, mode, and a PATH string, return the path which
conforms to the given mode on the PATH, or None if there is no such
file.
`mode` defaults to os.F_OK | os.X_OK. `path` defaults to the result
of os.environ.get("PATH"), or can be overridden with a custom search
path.
