Perl code:

use Geo::GDAL;

my $methods = Geo::OSR::GetProjectionMethods;
for my $method (@$methods) {
    my ($params, $projection) = 
Geo::OSR::GetProjectionMethodParameterList($method);
    print "PROJECTION METHOD: $projection\n";
    for my $param (@$params) {
        my ($name, $type, $defaultval) = 
Geo::OSR::GetProjectionMethodParamInfo($method, $param);
        print "  PARAMETER: $name, TYPE: $type, DEFAULT VALUE: 
$defaultval\n";
    }
}

Lists human readable names of known projection methods and their 
parameters with types and default values.
