==> Caveats
The command has been installed with the prefix "g".
If you do not want the prefix, install using the "with-default-names" option.

If you need to use these commands with their normal names, you
can add a "gnubin" directory to your PATH from your bashrc like:
  PATH="/usr/local/opt/gnu-sed/libexec/gnubin:$PATH"

Additionally, you can access their man pages with normal names if you add
the "gnuman" directory to your MANPATH from your bashrc as well:
  MANPATH="/usr/local/opt/gnu-sed/libexec/gnuman:$MANPATH"

==> Installing d12frosted/emacs-plus/emacs-plus dependency: texinfo

######################################################################## 100.0%
==> Pouring texinfo-6.5.high_sierra.bottle.tar.gz
==> Caveats
This formula is keg-only, which means it was not symlinked into /usr/local,
because software that uses TeX, such as lilypond and octave, require a newer
version of these files.

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

For compilers to find this software you may need to set:
    LDFLAGS:  -L/usr/local/opt/texinfo/lib

==> Caveats
This formula is keg-only, which means it was not symlinked into /usr/local,
because this is an alternate version of another formula.

If you need to have this software first in your PATH run:
  echo 'export PATH="/usr/local/opt/imagemagick@6/bin:$PATH"' >> ~/.bash_profile

For compilers to find this software you may need to set:
    LDFLAGS:  -L/usr/local/opt/imagemagick@6/lib
    CPPFLAGS: -I/usr/local/opt/imagemagick@6/include
For pkg-config to find this software you may need to set:
