+* works on windows, linux and macos
+* assumes `copyparty-sfx.py` was renamed to `copyparty.py` in the same folder as `copyparty.bat`

+### [`index.html`](index.html)
+* drop-in redirect from an httpd to copyparty
+* assumes the webserver and copyparty is running on the same server/IP

+# hi
+this showcases my worst idea yet; *extending markdown with inline javascript*
+
+due to obvious reasons it's disabled by default, and can be enabled with `-emp`
+
+the examples are by no means correct, they're as much of a joke as this feature itself
+
+
+### sub-header
+nothing special about this one
+
+
+## except/
+this one becomes a hyperlink to ./except/ thanks to
+* the `copyparty_pre` plugin at the end of this file
+* which is invoked as a markdown filter every time the document is modified
+* which looks for headers ending with a `/` and erwrites all headers below that
+
+it is a passthrough to the markdown extension api, see https://marked.js.org/using_pro
+
+in addition to the markdown extension functions, `ctor` will be called on document init
+
+
+### these/
+and this one becomes ./except/these/
+
+
+#### ones.md
+finally ./except/these/ones.md
+
+
+### also-this.md
+whic hshoud be ./except/also-this.md
+
+
+
+
+# ok
+now for another extension type, `copyparty_post` which is called to manipulate the generated dom instead
+
+`copyparty_post` can have the following functions, all optional
+* `ctor` is called on document init
+* `render` is called when the dom is done but still in-memory
+* `render2` is called with the live browser dom as-displayed
+
+## post example
+
+the values in the `ex:` columns are linkified to `example.com/$value`
+
+| ex:foo       | bar      | ex:baz |
+| ------------ | -------- | ------ |
+| asdf         | nice     | fgsfds |
+| more one row | hi hello | aaa    |
+
+and the table can be sorted by clicking the headers
+
+the difference is that with `copyparty_pre` you'll probably break various copyparty features but if you use `copyparty_post` then future copyparty versions will probably break you
+
+
+
+
+# heres the plugins
+if there is anything below ths line in the preview then the plugin feature is disabled (good)
