Find the full path to specified files.
Reports the full paths to the files given through fname. We look for the file in (1) the current directory, (2) in $GMT_USERDIR (if defined), (3) in $GMT_DATADIR (if defined), or (4) in $GMT_CACHEDIR (if defined).
fname can also be a downloadable file (either a full URL, a @file special file for downloading from the GMT Site Cache, or @earth_relief_* topography grids). In these cases, use option download to set the desired behavior. If download is not used (or False), the file will not be found.
