htprep.icn: Program to prepare HTML files

usage:  htprep [file]

Htprep is a filter for preparing HTML files (used, e.g., by Mosaic)
from a simpler and less error-prone input language.

The following transformations are applied:

     input           output
     ------------    ------------
     {}
     {!comment}      <!--comment-->
     {tag}           <tag>
     {tag ... }      <tag> ... <\tag>
       att=val...      att="val"...
     {@url ...       <a href="url" ...
     {:lbl ...       <a name="lbl" ...

Any input character can be preceded by a backslash (\) to prevent
special interpretation by htprep.

Output is normally to stdout, but the command
     {divert fname}
redirects output to the named file.  This can be used to produce
multiple related output files from a single input file.
