in themes/default/assets/_attachment.html:

I replaced this:

<% available_files = Array.new
         available_files << @asset.default_attachment.filename.gsub(/^[^.]+\./,'').upcase
         @asset.other_attachments.each do |attachment|
           available_files << attachment.filename.gsub(/^[^.]+\./,'').upcase

    # * +convert_options+: When creating thumbnails, use this free-form options
    #   field to pass in various convert command options.  Typical options are "-strip" to
    #   remove all Exif data from the image (save space for thumbnails and avatars) or
    #   "-depth 8" to specify the bit depth of the resulting conversion.  See ImageMagick
    #   convert documentation for more options: (http://www.imagemagick.org/script/convert.php)
    #   Note that this option takes a hash of options, each of which correspond to the style
    #   of thumbnail being generated. You can also specify :all as a key, which will apply
    #   to all of the thumbnails being generated. If you specify options for the :original,
    #   it would be best if you did not specify destructive options, as the intent of keeping
    #   the original around is to regenerate all the thumbnails when requirements change.

/**
 * GC (Garbage Collection) Module
 *
 * Note: Since we rely on Java's memory model we can't provide the
 * kind of control over garbage collection that MRI provides.  Also note
 * that since all Ruby libraries make GC assumptions based on MRI's GC
 * that we decided to no-op explicit collection through these APIs.
 * You can use Java Integration in your libraries to force a Java
 * GC (assuming you really want to).

# how to implement once ?
# it should evaluate the block only once per "once" call
# but it should evaluate again once if another "once" is in the view
# the following should render 1 1
