==> Summary
🍺  /usr/local/Cellar/git/2.19.0_1: 1,512 files, 318.2MB
==> Caveats
==> gettext
gettext 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 gettext first in your PATH run:
  echo 'export PATH="/usr/local/opt/gettext/bin:$PATH"' >> ~/.bash_profile
For compilers to find gettext you may need to set:
  export LDFLAGS="-L/usr/local/opt/gettext/lib"
  export CPPFLAGS="-I/usr/local/opt/gettext/include"
