projsync is a program that downloads remote resource files into a local directory. This is an alternative
       to downloading a proj-data-X.Y.Z archive file, or using the on-demand networkingcapabilities of PROJ.

       The following control parameters can appear in any order:

       --endpointURL
              Defines  the  URL  where  to  download  the master files.geojson file and then the resource files.
              Defaults to the value set in proj.ini--local-geojson-fileFILENAME
              Defines the filename for  the  master  GeoJSON  files  that  references  resources.   Defaults  to
              ${endpoint}/files.geojson--user-writable-directory
              Specifies  that  resource  files  must  be  downloaded in the userwritabledirectory. This is the
              default.

       --system-directory
              Specifies  that  resource  files  must  be  downloaded  in  the  ${installation_prefix}/share/proj
              directory. The user launching projsync should make sure it has writing rights in that directory.

       --target-dirDIRNAME
              Directory into which resource files must be downloaded.

       --bboxwest_long,south_lat,east_long,north_lat
              Specify  an  area  of  interest  to  restrict  the resources to download.  The area of interest is
              specified as a bounding box with geographic coordinates, expressed in  degrees  in  a  unspecified
              geographic  CRS.   west_long  and  east_long  should be in the [-180,180] range, and south_lat and
              north_lat in the [-90,90]. west_long is generally lower than east_long, except in the  case  where
              the area of interest crosses the antimeridian.

       --spatial-testcontains|intersects
              Specify  how the extent of the resource files are compared to the area of use specified explicitly
              with --bbox.  By default, any resource files whose extent intersects the value specified by --bbox
              will be selected.  If using the contains strategy, only resource files whose extent  is  contained
              in the value specified by --bbox will be selected.

       --source-idID
              Restrict  resource files to be downloaded to those whose source_id property contains the ID value.
              Specifying ? as ID will list all possible values.

       --area-of-useNAME
              Restrict resource files to be downloaded to those whose area_of_use  property  contains  the  NAME
              value. Specifying ? as NAME will list all possible values.

       --fileNAME
              Restrict  resource  files  to  be downloaded to those whose name property contains the NAME value.
              Specifying ? as NAME will list all possible values.

       --all  Ask to download all files.

       --exclude-world-coverage
              Exclude files which have world coverage.

       -q/--quiet
              Quiet mode

       --verbose
              New in version 8.1.

              Verbose mode (more than default)

       --dry-run
              Simulate the behavior of the tool without downloading resource files.

       --list-files
              List file names, with the source_id and area_of_use properties.

       --no-version-filtering
              New in version 8.1.

              By default, projsync only downloads files that are compatible of the PROJ_DATA.VERSION metadata of
              proj.db, taking into account the  version_added  and  version_removed  properties  of  entries  in
              files.geojson.   When  specifying  this  switch,  all  files  referenced  in files.geojson will be
              candidate (combined with other filters).

       At least one of  --list-files,  --file,  --source-id, --area-of-use,  --bbox or  --all must be specified.

       Options --file,  --source-id, --area-of-use and --bbox are combined with a AND logic.

       1. Download all resource files

          projsync --all

       2. Download resource files covering specified point and attributed to an agency

          projsync --source-id fr_ign --bbox 2,49,2,49
