=head1 NAME

DBIx::Class::Helper::Schema::DidYouMean - Nice error messages when you misspell the name of a ResultSet

=head1 SYNOPSIS

 package MyApp::Schema;

 __PACKAGE__->load_components('Helper::Schema::DidYouMean');

Elsewhere:

 $schema->resultset('Usre')->search(...)->...

And a nice exception gets thrown:

 The ResultSet "Usre" is not part of your schema.
 
 To help you debug this issue, here's a list of the actual sources that the
 schema knows about:
 
     Account
     Permission
     Role
   * User <-- Possible Match

=head1 DESCRIPTION

This helper captures errors thrown when you use the C<resultset> method on your
schema and typo the source name.  It tries to highlight the best guess as to
which you meant to type.
