| feaLib: Read/write OpenType feature files |
| ######################################### |
| |
| fontTools' ``feaLib`` allows for the creation and parsing of Adobe |
| Font Development Kit for OpenType feature (``.fea``) files. The syntax |
| of these files is described `here <https://adobe-type-tools.github.io/afdko/OpenTypeFeatureFileSpecification.html>`_. |
| |
| The :class:`fontTools.feaLib.parser.Parser` class can be used to parse files |
| into an abstract syntax tree, and from there the |
| :class:`fontTools.feaLib.builder.Builder` class can add features to an existing |
| font file. You can inspect the parsed syntax tree, walk the tree and do clever |
| things with it, and also generate your own feature files programmatically, by |
| using the classes in the :mod:`fontTools.feaLib.ast` module. |
