Manakin: where to find a tutorial

Question

Hi,

maybe you can help me here, although I know the chances are low but I'm getting desperate :). I'm working with Dspace and Manakin and I'm having some problems with the themes.

For example, to show an specific issue, I'm trying to overwrite the content display:

<xsl:template match="mets:fileGrp[@USE='CONTENT']">                
   <h2><i18n:text>xmlui.dri2xhtml.METS-1.0.item-files-head</i18n:text></h2>
   <xsl:apply-templates select="mets:file">
      <xsl:sort data-type="number"  select="boolean(./@ID=$primaryBitstream)" order="descending" />
      <xsl:sort select="mets:FLocat[@LOCTYPE='URL']/@xlink:title"/> 
      <xsl:with-param name="context" select="$context"/>
   </xsl:apply-templates>
</xsl:template>   

but it doesn't display anything.

If anyone knows a good tutorial, or has a well documented sample I can use I would be eternally grateful.

Best regards.
