Comment:
I have personal cfdg package. I suck at C/CPP, so I don't feel like maintain it officially.

```sh
# Template file for 'cfdg'
pkgname=cfdg
version=3.3
revision=1
wrksrc=context-free-Version${version}
build_style=gnu-makefile
make_install_args="PREFIX=/usr DESTDIR=${DESTDIR}"
hostmakedepends="flex bison"
makedepends="icu-devel libpng-devel libatomic-devel"
short_desc="Context Free is a program that generates images from grammar"
maintainer="Daniel Lewan <vision360.daniel@gmail.com>"
license="GPL-2.0-or-later"
homepage="https://github.com/MtnViewJohn/context-free"
distfiles="https://github.com/MtnViewJohn/context-free/archive/Version${version}.tar.gz"
checksum=@d5c756fd46db78aca944e40825f4f1cb01410cd6168c7bfb4108e920c16a3bb9

do_build() {
	make -j $(nproc)
}

post_install() {
		rm -rf ${DESTDIR}/usr/local
		vbin ${wrksrc}/cfdg
		vman ${wrksrc}/cfdg.1
}
```
