fzg - oss pixel font, combining fairfax, zlabs and galmuri
[fzg] compile tt/ot only
do u know? eot and woff formats are just a compression method of specific ot font. like otf.gz file. ttf file can be treated as otf too.

+
导航到 [tools/build.py](../tools/build.py)，点击 `Python Debugger: Debug Python File` 开始编译。你也可以使用 `python -m tools.build`
