+=head1 NAME
+
+Devel::REPL::Profile
+
+=head1 SYNOPSIS
+
+ package Devel::REPL::Profile::MyProject;
+ 
+ use Moose;
+ use namespace::clean -except => [ 'meta' ];
+ 
+ with 'Devel::REPL::Profile';
+ 
+ sub apply_profile {
+     my ($self, $repl) = @_;
+     # do something here
+ }
+

+
+=head1 DESCRIPTION
+
+For particular projects you might well end up running the same commands each
+time the REPL shell starts up - loading Perl modules, setting configuration,
+and so on.
+
+A mechanism called I<profiles> exists to let you package and distribute these
+start-up scripts, as Perl modules.
+
+=head1 USAGE
+
+Quite simply, follow the L</"SYNOPSIS"> section above to create a boilerplate
+profile module. Within the C<apply_profile> method, the C<$repl> variable can
+be used to run any commands as the user would, within the context of their
+running C<Devel::REPL> shell instance.
+
+For example, to load a module, you might have something like this:
+
+ sub apply_profile {
+     my ($self, $repl) = @_;
+     $repl->eval('use Carp');
+ }
+
+As you can see, the C<eval> method is used to run any code. The user won't see
+any output from that, and the code can "safely" die without destroying the
+REPL shell. The return value of C<eval> will be the return value of the code
+you gave, or else if it died then a C<Devel::REPL::Error> object is returned.
+
+If you want to load a C<Devel::REPL> plugin, then use the following method:
+
+ $repl->load_plugin('Timing');
+
+The C<load_plugin> and C<eval> methods should cover most of what you would
+want to do before the user has access to the shell. Remember that plugin
+features are immediately available, so you can load for example the C<LexEnv>
+plugin, and then declare C<my> variables which the user will have access to.
+
+=head2 Selecting a Profile
+
+To run the shell with a particular profile, use the following command:
+
+ system$ re.pl --profile MyProject
+
+When the profile name is unqualified, as in the above example, the profile is
+assumed to be in the C<Devel::REPL::Profile::> namespace. Otherwise if you
+pass something which contains the C<::> character sequence, it will be loaded
+as-is.
