# Package `formal-grammar`
This package provides an easy way to write formal grammars.
To use it, run the following commands:
```
$ latex formal-grammar.ins
$ pdflatex formal-grammar.dtx
```
The first command generates the file `formal-grammar.sty` that should be placed
in the same folder than your main document. The second command generates the
file `formal-grammar.pdf` (you may require multiple runs to adjust internal
references), which is the documentation for the package.
