+Readonly/XS version 1.04
+========================
+
+This is a companion module to Readonly.pm. You do not use
+Readonly::XS directly. Instead, once it is installed, Readonly.pm
+will detect this and will use it for creating read-only scalars. This
+results in a significant speed improvement. This does not speed up
+read-only arrays or hashes.
+
+INSTALLATION
+
+To install this module, do the standard Perl module four-step:
+
+ perl Makefile.PL
+ make
+ make test
+ make install
+
+DEPENDENCIES
+
+None, although it's useless without Readonly.pm.

+=head1 SYNOPSIS
+
+ Install this module, but do not use it.
+
+=head1 DESCRIPTION
+
+The Readonly module (q.v.) is an effective way to create
+non-modifiable variables. However, it's relatively slow.
+
+The reason it's slow is that is implements the read-only-ness of
+variables via tied objects. This mechanism is inherently slow. Perl
+simply has to do a lot of work under the hood to make tied variables
+work.
+
+This module corrects the speed problem, at least with respect to
+scalar variables. When Readonly::XS is installed, Readonly uses it to
+access the internals of scalar variables. Instead of creating a
+scalar variable object and tying it, Readonly simply flips the
+SvREADONLY bit in the scalar's FLAGS structure.
+
+Readonly arrays and hashes are not sped up by this, since the
+SvREADONLY flag only works for scalars. Arrays and hashes always use
+the tie interface.
+
+Why implement this as a separate module? Because not everyone can use
+XS. Not everyone has a C compiler. Also, installations with a
+statically-linked perl may not want to recompile their perl binary
+just for this module. Rather than render Readonly.pm useless for
+ these people, the XS portion was put into a separate module.
+
+Programs that you write do not need to know whether Readonly::XS is
+installed or not. They should just "use Readonly" and let Readonly
+worry about whether or not it can use XS. If the Readonly::XS is
+present, Readonly will be faster. If not, it won't. Either way, it
+will still work, and your code will not have to change.
+
+Your program can check whether Readonly.pm is using XS or not by
+examining the $Readonly::XSokay variable. It will be true if the
+XS module was found and is being used. Please do not change this
+variable.
