+    Get the version (PEP 440).
+
+    A biased approach to the PEP 440 semantic version.
+
+    Provides a tuple structure which is sorted for comparisons `v1 > v2` etc.
+      (major, minor, micro, release type, pre-release build, post-release build, development release build)
+    Release types are named in is such a way they are comparable with ease.
+    Accessors to check if a development, pre-release, or post-release build. Also provides accessor to get
+    development status for setup files.
+
+    How it works (currently):
+
+    - You must specify a release type as either `final`, `alpha`, `beta`, or `candidate`.
+    - To define a development release, you can use either `.dev`, `.dev-alpha`, `.dev-beta`, or `.dev-candidate`.
+      The dot is used to ensure all development specifiers are sorted before `alpha`.
+      You can specify a `dev` number for development builds, but do not have to as implicit development releases
+      are allowed.
+    - You must specify a `pre` value greater than zero if using a prerelease as this project (not PEP 440) does not
+      allow implicit prereleases.
+    - You can optionally set `post` to a value greater than zero to make the build a post release. While post releases
+      are technically allowed in prereleases, it is strongly discouraged, so we are rejecting them. It should be
+      noted that we do not allow `post0` even though PEP 440 does not restrict this. This project specifically
+      does not allow implicit post releases.
+    - It should be noted that we do not support epochs `1!` or local versions `+some-custom.version-1`.
+
+    Acceptable version releases:
+
+    ```
+    Version(1, 0, 0, "final")                    1.0
+    Version(1, 2, 0, "final")                    1.2
+    Version(1, 2, 3, "final")                    1.2.3
+    Version(1, 2, 0, ".dev-alpha", pre=4)        1.2a4
+    Version(1, 2, 0, ".dev-beta", pre=4)         1.2b4
+    Version(1, 2, 0, ".dev-candidate", pre=4)    1.2rc4
+    Version(1, 2, 0, "final", post=1)            1.2.post1
+    Version(1, 2, 3, ".dev")                     1.2.3.dev0

+Format a pretty string of a `SoupSieve` object for easy debugging.
+
+This won't necessarily support all types and such, and definitely
+not support custom outputs.
+
+It is mainly geared towards our types as the `SelectorList`
+object is a beast to look at without some indentation and newlines.
+The format and various output types is fairly known (though it
+hasn't been tested extensively to make sure we aren't missing corners).
+
+Example:
+-------
+```
