How to convert gdalinfo output to JSON format?

Which is the manual page of ogr2ogr?
It is understandable to read only the manual page of ogr2ogr http://www.gdal.org/ogr2ogr.html and miss the page about options which are general to all OGR utilities https://gdal.org/programs/vector_common_options.html because the first one does not mention that the latter exists.
