Class	DiffPath	Base type for command object that compare files
Class	DiffKindChange	Special differ for file kind changes.
Class	DiffDirectory	No class docstring; 1/1 methods documented
Class	DiffSymlink	No class docstring; 1/2 methods documented
Class	DiffText	No class docstring; 2/3 methods documented

Class	DiffTree	Provides textual representations of the difference between two trees.
Class	_PrematchedMatcher	Allow SequenceMatcher operations to use predetermined blocks
Function	_spawn_external_diff	Spawn the externall diff process, and return the child handle.
Function	_get_tree_to_diff	Undocumented

def _spawn_external_diff(diffcmd, capture_errors=True):

Spawn the externall diff process, and return the child handle.

Parameters	diffcmd	The command list to spawn
	capture_errors	Capture stderr as well as setting LANG=C and LC_ALL=C. This lets us read and understand the output of diff, and respond to any errors.
Returns	A Popen object.

def get_trees_and_branches_to_diff(path_list, revision_specs, old_url, new_url, apply_view=True):

Get the trees and specific files to diff given a list of paths.

This method works out the trees to be diff'ed and the files of interest within those trees.

Parameters	path_list	the list of arguments passed to the diff command
	revision_specs	Zero, one or two RevisionSpecs from the diff command line, saying what revisions to compare.
	old_url	The url of the old branch or tree. If None, the tree to use is taken from the first path, if any, or the current working tree.
	new_url	The url of the new branch or tree. If None, the tree to use is taken from the first path, if any, or the current working tree.
	apply_view	if True and a view is set, apply the view or check that the paths are within it
Returns	a tuple of (old_tree, new_tree, old_branch, new_branch, specific_files, extra_trees) where extra_trees is a sequence of additional trees to search in for file-ids.

def show_diff_trees(old_tree, new_tree, to_file, specific_files=None, external_diff_options=None, old_label='a/', new_label='b/', extra_trees=None, path_encoding='utf8', using=None):

Show in text form the changes from one tree to another.

to_file: The output stream.
specific_files: Include only changes to these files - None for all changes.
external_diff_options: If set, use an external GNU diff and pass these options.
extra_trees: If set, more Trees to use for looking up file ids
path_encoding: If set, the path will be encoded as specified, otherwise is supposed to be utf8
