<<-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.
|
|
|
|
Unless you are using Homebrew's Python, both the bindings and the
|
|
additional tools will be unusable unless the following directory is added to
|
|
the PYTHONPATH:
|
|
|
|
#{HOMEBREW_PREFIX}/lib/#{which_python}/site-packages
