!Short: - Short Entries

    Purpose
    Short entries provide a concise summary of a topic and serve as an easy-
    to-scan pointer to a more complete description.

    Format:
         !short:[line-of-text]                                          
              text of long entry                                        
         [!seealso: references]                                         

    or

         !short:[line-of-text]                                          
         !file: filename.ngo                                            

    Description
    A short entry is a single line of text. Short entries generally appear
    as part of a list with other short entries; the list can be thought of
    as an index into longer, more complete descriptions. These underlying
    long descriptions are accessed via the Expand menu of the Hypertext
    Database.

    A short entry can point to either a single long entry or to another
    list of short entries. A short entry must begin with the command
    !short:, starting in column 1. All text after the colon, including
    spaces and tabs, will appear in the text of the short entry in the
    database, exactly as it was typed into the Data Text File (with the
    exception of the special handling of ^ (caret) character sequences).
