==> Caveats
This formula is keg-only, which means it was not symlinked into /usr/local,
because macOS provides the BSD gettext library & some software gets confused if both are in the library path.

If you need to have this software first in your PATH run:
  echo 'export PATH="/usr/local/opt/gettext/bin:$PATH"' >> ~/.zshrc

For compilers to find this software you may need to set:
    LDFLAGS:  -L/usr/local/opt/gettext/lib
    CPPFLAGS: -I/usr/local/opt/gettext/include
