Arch Linux

Description:

`espeak-ng` appears to be a drop-in replacement for `espeak`, if some symlinks are set. Consider doing that.

In the `PKGBUILD`s `package()`-function, adding the following lines at the end did make it compatible for me:

```
# Compatibilty-link for 'espeak':
cd "${pkgdir}/usr/lib"
for _ng_lib in libespeak-ng.so*; do
ln -sv "${_ng_lib}" $(sed -E 's|\-ng\.|.|' <<< "${_ng_lib}"})
done
cd "${pkgdir}/usr/lib/pkgconfig"
ln -sv "espeak-ng.pc" "espeak.pc"
cd "${pkgdir}/usr/share"
ln -sv "espeak-ng-data" "espeak-data"
```

And then adding `provides=("espeak=${pkgver}")` did make the dependency available to `pacman`.
