def caveats
<<-EOS
This version of GDAL was built with Python support. In addition to providing
modules that makes GDAL functions available to Python scripts, the Python
binding provides ~18 additional command line tools. However, both the Python
bindings and the additional tools will be unusable unless the following
directory is added to the PYTHONPATH:
#{HOMEBREW_PREFIX}/lib/python
