5.4.2.3 Link types for 'hypertex'
.................................

'name'
     Go to a "named destination". The label is the destination name. All
     destinations in HyperTeX are named destinations. This is the
     default type.

     Example: '\hlstart{name}{}{dest123}Link to dest123\hlend'

'url'
     Go to a URL. The label is the URL.

     Example:

          \hlstart{url}{}{http://tug.org/eplain/}Eplain home\hlend

'filename'
     Go to a named destination in another file. The label is the
     destination name. The file name is specified by the 'file' option.
     The file name extension can be specified separately by the 'ext'
     option. The idea is to set the 'ext' option globally at the
     beginning of the document to avoid hard-coding the extension
     together with the file name within each link--HyperTeX is not
     restricted to any single output format, it can be DVI, PDF,
     possibly other formats.

     Example:

          \hlopts{ext=.pdf}
          \hlstart{filename}{file=book}{dest123}
            Link to dest123 in file `book.pdf'\hlend

'raw'
     The link specification (in the form of a HyperTeX '\special') is
     taken from the command sequence '\CS', where CS is the value of the
     'cmd' option. In the definition of '\CS', use '\@hllabel' to refer
     to the hyperlink label. Use the predefined command '\hlhash' to
     insert the '#' characters. This option is intended to be used with
     linkgroups (Note: Setting hyperlink types and options), as it
     does not make sense in a direct call to '\hlstart'--you can just
     call the raw command.

     Example:

          \makeatletter
          \def\mylink{\special{html:<a href="\hlhash\@hllabel">}}
          \resetatcatcode
          \hlstart{raw}{cmd=mylink}{SpecialDest}
            Link to the special destination.\hlend
