<<-EOS.undent
A top-level "man" directory was found
Homebrew requires that man pages live under share.
This can often be fixed by passing "--mandir=\#{man}" to configure.

<<-EOS.undent
JARs were installed to "#{formula.lib}"
Installing JARs to "lib" can cause conflicts between packages.
For Java software, it is typically better for the formula to
install to "libexec" and then symlink or wrap binaries into "bin".
See "activemq", "jruby", etc. for examples.
The offending files are:
#{jars * "\n "}

<<-EOS.undent
Generic binaries were installed to "#{bin}"
Binaries with generic names are likely to conflict with other software,
and suggest that this software should be installed to "libexec" and then
symlinked as needed.
The offending files are:
