How to utilize the functions of OSClass?

Question

I want to create a new .php file and I want to utilize the functions within the OSclass Codex. For instance this code won't work because I haven't imported all the functions and dependencies. How exactly do I accomplish this.

<?php osc_query_item("region_name=Madrid");
if( osc_count_custom_items() == 0) { ?>
    <p class="empty"><?php _e('No Listings', 'modern') ; ?></p>
<?php } else { ?>
    <table border="0" cellspacing="0">
         <tbody>
            <?php $class = "even"; ?>
            <?php while ( osc_has_custom_items() ) { ?>
             <tr class="<?php echo $class. (osc_item_is_premium()?" premium":"") ; ?>">
                    <?php if( osc_images_enabled_at_items() ) { ?>
                     <td class="photo">
                        <?php if( osc_count_item_resources() ) { ?>
                            <a href="<?php echo osc_item_url() ; ?>">
                                <img src="<?php echo osc_resource_thumbnail_url() ; ?>" width="75" height="56" title="<?php echo osc_item_title(); ?>" alt="<?php echo osc_item_title(); ?>" />
                            </a>
                        <?php } else { ?>
                            <img src="<?php echo osc_current_web_theme_url('images/no_photo.gif') ; ?>" alt="" title=""/>
                        <?php } ?>
                     </td>
                    <?php } ?>
                     <td class="text">
                         <h3><a href="<?php echo osc_item_url() ; ?>"><?php echo osc_item_title() ; ?></a></h3>
                         <p><strong><?php if( osc_price_enabled_at_items() ) { echo osc_item_formated_price() ; ?> - <?php } echo osc_item_city(); ?> (<?php echo osc_item_region();?>) - <?php echo osc_format_date(osc_item_pub_date()); ?></strong></p>
                         <p><?php echo osc_highlight( strip_tags( osc_item_description() ) ) ; ?></p>
                     </td>                                       
                 </tr>
                <?php $class = ($class == 'even') ? 'odd' : 'even' ; ?>
            <?php } ?>
        </tbody>
    </table>
<?php }; ?>

What you'll want to do is a custom page. In Osclass, custom pages are brought by plugins. If you need a tutorial about creating a plugin in Osclass 3.3+, here's one : How to create plugins for Osclass.

If your curious about Osclass internals, all Osclass functions (helpers) are loaded in the /oc-load.php at the root of your installation.
