title: List all files in a homebrew package
body: <p>How can I get <code>homebrew</code> to list out all files installed for a package? For example, when I run <code>brew list</code> for the exim package, I get these files:</p>
  
  <pre><code>$ brew list exim
  /usr/local/Cellar/exim/4.80.1/bin/exiwhat
  /usr/local/Cellar/exim/4.80.1/bin/exiqsumm
  /usr/local/Cellar/exim/4.80.1/bin/exiqgrep
  /usr/local/Cellar/exim/4.80.1/bin/exipick
  /usr/local/Cellar/exim/4.80.1/bin/exinext
  /usr/local/Cellar/exim/4.80.1/bin/eximstats
  /usr/local/Cellar/exim/4.80.1/bin/exim_tidydb
  /usr/local/Cellar/exim/4.80.1/bin/exim_lock
  /usr/local/Cellar/exim/4.80.1/bin/exim_fixdb
  /usr/local/Cellar/exim/4.80.1/bin/exim_dumpdb
  /usr/local/Cellar/exim/4.80.1/bin/exim_dbmbuild
  /usr/local/Cellar/exim/4.80.1/bin/exim_ctl
  /usr/local/Cellar/exim/4.80.1/bin/exim_checkaccess
  /usr/local/Cellar/exim/4.80.1/bin/exim-4.80.1-3
  /usr/local/Cellar/exim/4.80.1/bin/exim
  /usr/local/Cellar/exim/4.80.1/bin/exigrep
  /usr/local/Cellar/exim/4.80.1/bin/exicyclog
  /usr/local/Cellar/exim/4.80.1/share/man/man8/exim.8
  </code></pre>
  
  <p>But there are files added to the system that is not in the list above. For example:</p>
  
  <pre><code>$ ls -ld /usr/local/etc/exim.conf 
  -rw-r--r--  1 hanxue  admin  35904 Sep 25 21:11 /usr/local/etc/exim.conf
  </code></pre>
