The C<JSON> constant returns the selected implementation module's name for
use as a class name - so:
- my $json_obj = JSON->new; # returns a Cpanel::JSON::XS or JSON::PP object
+ my $json_obj = JSON()->new; # returns a Cpanel::JSON::XS or JSON::PP object
and that object can then be used normally:
my $data_structure = $json_obj->decode($json_text); # etc.
+The use of parentheses here is optional, and only used as a hint to the reader
+that this use of C<JSON> is a I<subroutine> call, I<not> a class name.

To include JSON-aware booleans (C<true>, C<false>) in your data, just do:
use JSON::MaybeXS;
- my $true = JSON->true;
- my $false = JSON->false;
+ my $true = JSON()->true;
+ my $false = JSON()->false;

+=head1 INSTALLATION
+
+At installation time, F<Makefile.PL> will attempt to determine if you have a
+working compiler available, and therefore whether you are able to run XS code.
+If so, L<Cpanel::JSON::XS> will be added to the prerequisite list, unless
+L<JSON::XS> is already installed at a high enough version. L<JSON::XS> may
+also be upgraded to fix any incompatibility issues.
+
+Because running XS code is not mandatory and L<JSON::PP> (which is in perl
+core) is used as a fallback backend, this module is safe to be used in a suite
+of code that is fatpacked or installed into a restricted-resource environment.
+
+You can also prevent any XS dependencies from being installed by setting
+C<PUREPERL_ONLY=1> in F<Makefile.PL> options (or in the C<PERL_MM_OPT>
+environment variable), or using the C<--pp> or C<--pureperl> flags with the
+L<cpanminus client|cpanm>.
