def check_manpages
# Check for man pages that aren't in share/man
return unless (formula.prefix/"man").directory?
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`.

def check_infopages
# Check for info pages that aren't in share/info
return unless (formula.prefix/"info").directory?
A top-level "info" directory was found
Homebrew suggests that info pages live under share.
This can often be fixed by passing `--infodir=\#{info}` to `configure`.
return unless formula.lib.directory?
jars = formula.lib.children.select { |g| g.extname == ".jar" }
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

return unless formula.lib.directory?

Non-libraries were installed to "#{formula.lib}"
Installing non-libraries to "lib" is discouraged.

return unless bin.directory?
non_exes = bin.children.select { |g| g.directory? || !g.executable? }

The offending files are:
generic_names = %w[service start stop]
generics = bin.children.select { |g| generic_names.include? g.basename.to_s }
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:
#{generics * "\n "}
EOS
pth_found = Dir["#{lib}/python{2.7,3}*/site-packages/easy-install.pth"].map { |f| File.dirname(f) }
easy-install.pth files were found
These .pth files are likely to cause link conflicts. Please invoke
setup.py using Language::Python.setup_install_args.
