 Devel::REPL::Plugin::Nopaste - #nopaste to upload session's input and output
 
+=head1 COMMANDS
+
+This module provides these commands to your Devel::REPL shell:
+
+=head2 #nopaste
+
+The C<#nopaste> sends a transcript of your session to a nopaste
+site.
+
+=head2 #pastetitle
+
+The C<#pastetitle> command allows you to set the title of the paste on
+the nopaste site. For example:
+
+C<#pastetitle example of some code>
+
+defaults to C<'Devel::REPL session'>.
+
+=head1 CONFIGURATION
+
+=head2 nopaste_format
+
+The format sent to the nopaste server can be adjusted with the
+C<nopaste_format> option. By default, the output of each perl
+statement is commented out, and the perl statements themselves are
+not. This can be reversed by setting the C<nopaste_format> attribute
+to C<comment_code> like this in your re.pl file:
+
+C<< $_REPL->nopaste_format( 'comment_code' ); >>
+
+The default of commenting out the output would be set like this:
+
+C<< $_REPL->nopaste_format( 'comment_output' ); >>
+
+These options can be set during a L<Devel::REPL> session, but only affect
+the future parts of the session, not the past parts.
