    +# _kewt_
    +
    +_kewt_ is a minimalist ssg inspired by _[werc](http://werc.cat-v.org/)_ and _[kew](https://github.com/uint23/kew)_
    +
    +It's meant to be a static site generator, like _[kew](https://github.com/uint23/kew)_ but use only default (POSIX) tooling, like _[werc](http://werc.cat-v.org/)_ (and definitely unlike _[kew](https://github.com/uint23/kew)_)
    +
    +## Features
    +
    +- No dependencies
    +- Supports many embed types
    +- Automatic css variable replacement for older browsers
    +- Automatic inlining and embedding of many filetypes with `\![link]` or `\![alt](link)`
    +- Inline html support
    +- MFM `$font` and `\` tags
    +- Admonition support (that's what the blocks like the warning block below are called)
    +
    +If you want to **force** a file to be inlined, use `\!![]` instead of `\![]`
    +
    +## Credits
    +
    +- Markdown to html conversion based on [markdown.bash](https://github.com/chadbraunduin/markdown.bash) by [chadbraunduin](https://github.com/chadbraunduin)
    +- Default css style and html template based on _[kew](https://github.com/uint23/kew)_ by [uint23](https://github.com/uint23)
