 r"""
-htmldocck.py is a custom checker script for Rustdoc HTML outputs.
-
-# How and why?
-
-The principle is simple: This script receives a path to generated HTML
-documentation and a "template" script, which has a series of check
-commands like `@has` or `@matches`. Each command is used to check if
-some pattern is present or not present in the particular file or in
-a particular node of the HTML tree. In many cases, the template script
-happens to be the source code given to rustdoc.
-
-While it indeed is possible to test in smaller portions, it has been
-hard to construct tests in this fashion and major rendering errors were
-discovered much later. This script is designed to make black-box and
-regression testing of Rustdoc easy. This does not preclude the needs for
-unit testing, but can be used to complement related tests by quickly
-showing the expected renderings.
-
-In order to avoid one-off dependencies for this task, this script uses
-a reasonably working HTML parser and the existing XPath implementation
-from Python's standard library. Hopefully, we won't render
-non-well-formed HTML.
-
-# Commands
-
-Commands start with an `@` followed by a command name (letters and
-hyphens), and zero or more arguments separated by one or more whitespace
-characters and optionally delimited with single or double quotes. The `@`
-mark cannot be preceded by a non-whitespace character. Other lines
-(including every text up to the first `@`) are ignored, but it is
-recommended to avoid the use of `@` in the template file.
-
-There are a number of supported commands:
-
-* `@has PATH` checks for the existence of the given file.
-
-  `PATH` is relative to the output directory. It can be given as `-`
-  which repeats the most recently used `PATH`.
-
-* `@hasraw PATH PATTERN` and `@matchesraw PATH PATTERN` checks
-  for the occurrence of the given pattern `PATTERN` in the specified file.
-  Only one occurrence of the pattern is enough.
-
-  For `@hasraw`, `PATTERN` is a whitespace-normalized (every consecutive
-  whitespace being replaced by one single space character) string.
-  The entire file is also whitespace-normalized including newlines.
-
-  For `@matchesraw`, `PATTERN` is a Python-supported regular expression.
-  The file remains intact but the regexp is matched without the `MULTILINE`
-  and `IGNORECASE` options. You can still use a prefix `(?m)` or `(?i)`
-  to override them, and `\A` and `\Z` for definitely matching
-  the beginning and end of the file.
-
-  (The same distinction goes to other variants of these commands.)
-
-* `@has PATH XPATH PATTERN` and `@matches PATH XPATH PATTERN` checks for
-  the presence of the given XPath `XPATH` in the specified HTML file,
-  and also the occurrence of the given pattern `PATTERN` in the matching
-  node or attribute. Only one occurrence of the pattern in the match
-  is enough.
-
-  `PATH` should be a valid and well-formed HTML file. It does *not*
-  accept arbitrary HTML5; it should have matching open and close tags
-  and correct entity references at least.
-
-  `XPATH` is an XPath expression to match. The XPath is fairly limited:
-  `tag`, `*`, `.`, `//`, `..`, `[@attr]`, `[@attr='value']`, `[tag]`,
-  `[POS]` (element located in given `POS`), `[last()-POS]`, `text()`
-  and `@attr` (both as the last segment) are supported. Some examples:
-
-  - `//pre` or `.//pre` matches any element with a name `pre`.
-  - `//a[@href]` matches any element with an `href` attribute.
-  - `//*[@class="impl"]//code` matches any element with a name `code`,
-    which is an ancestor of some element which `class` attr is `impl`.
-  - `//h1[@class="fqn"]/span[1]/a[last()]/@class` matches a value of
-    `class` attribute in the last `a` element (can be followed by more
-    elements that are not `a`) inside the first `span` in the `h1` with
-    a class of `fqn`. Note that there cannot be any additional elements
-    between them due to the use of `/` instead of `//`.
-
-  Do not try to use non-absolute paths, it won't work due to the flawed
-  ElementTree implementation. The script rejects them.
-
-  For the text matches (i.e. paths not ending with `@attr`), any
-  subelements are flattened into one string; this is handy for ignoring
-  highlights for example. If you want to simply check for the presence of
-  a given node or attribute, use an empty string (`""`) as a `PATTERN`.
-
-* `@count PATH XPATH COUNT` checks for the occurrence of the given XPath
-  in the specified file. The number of occurrences must match the given
-  count.
-
-* `@count PATH XPATH TEXT COUNT` checks for the occurrence of the given XPath
-  with the given text in the specified file. The number of occurrences must
-  match the given count.
-
-* `@snapshot NAME PATH XPATH` creates a snapshot test named NAME.
-  A snapshot test captures a subtree of the DOM, at the location
-  determined by the XPath, and compares it to a pre-recorded value
-  in a file. The file's name is the test's name with the `.rs` extension
-  replaced with `.NAME.html`, where NAME is the snapshot's name.
-
-  htmldocck supports the `--bless` option to accept the current subtree
-  as expected, saving it to the file determined by the snapshot's name.
-  compiletest's `--bless` flag is forwarded to htmldocck.
-
-* `@has-dir PATH` checks for the existence of the given directory.
-
-* `@files FOLDER_PATH [ENTRIES]`, checks that `FOLDER_PATH` contains exactly
-  `[ENTRIES]`.
-
-All conditions can be negated with `!`. `@!has foo/type.NoSuch.html`
-checks if the given file does not exist, for example.
