    GeoCouch Caveats:
    FYI:  geocouch installs as an extension of couchdb, so couchdb effectively
    becomes geocouch.  However, you can use couchdb normally (using geocouch
    extensions optionally).  NB: one exception: the couchdb test suite now
    includes several geocouch tests.
    To start geocouch manually and verify any geocouch version information (-V),
      ERL_FLAGS="-pa #{geocouch_share}/ebin"  couchdb -V
    For general convenience, export your ERL_FLAGS (erlang flags, above) in
    your login shell, and then start geocouch:
      export ERL_FLAGS="-pa #{geocouch_share}/ebin"
      couchdb
    Alternately, prepare launchctl to start/stop geocouch as follows:
      cp #{geocouch_share}/geocouch.plist ~/Library/LaunchAgents
      chmod 0644 ~/Library/LaunchAgents/geocouch.plist
      launchctl load ~/Library/LaunchAgents/geocouch.plist
    Then start, check status of, and stop geocouch with the following three
    commands.
      launchctl start geocouch
      launchctl list geocouch
      launchctl stop geocouch
    Finally, access, test, and configure your new geocouch with:
      http://127.0.0.1:5984
      http://127.0.0.1:5984/_utils/couch_tests.html?script/couch_tests.js
      http://127.0.0.1:5984/_utils
    And... relax.
    -=-
    To uninstall geocouch from your couchdb installation, uninstall couchdb
    and re-install it without the '--with-geocouch' option.
      brew uninstall couchdb
      brew install couchdb
    To see these instructions again, just run 'brew info couchdb'.
