  void somtSetOutputFile(inout FILE fp);
  // All template output will be directed to <fp>. Default is <stdout>.
  void somto(in string tmplt);
  // Outputs a template, <tmplt>, after substitution for any symbols
  // that occur in it.  Five substitutions are supported: simple,
  // list, comment, tab, and conditional.
  // Substitutable items in the template are bracketed with angle
  // brackets. (Backslash can be used to escape an angle bracket.)
  // Simple substitutions just replace a symbol with its value. If
  // the symbol has no value in this template object then the symbol
  // is replaced error string but no error is raised.
  // List substitution assumes that the symbol has a value in output
  // template list form. This is a newline separated string of
  // values. The list substitution specification consists of four
  // parts, a prefix, a symbol, a separator, and a list indicator.
  // prefixes and separators can only be composed of blanks, comma,
  // colons, and semi-colons.  The list indicator is "..." (three
  // periods).  For example, the list substitution
  // specification "<, name, ...> has a prefix of ", ", a symbol of
  // "name" and a separator of ", ".  The prefix will be used
  // whenever there is at least one item in the list and the separator
  // will be used between any two list items.  After the first items
  // of a list is placed each additional item is evaluated to see if
  // it would begin after the line length limit (set by
  // _set_somtLineLength), if it would then a new line is begun and the
  // value is placed directly under the first item.
  // Comment substitution assumes that the symbol has a value in
  // output template list form.  A comment specification consists of
  // a comment indicator followed by a symbol name. The comment
  // indicator is "--".  Eg, <-- classComment> is a valid comment
  // substitution specification.  The lines of the comment are output
  // according to the current comment style (see <somtCommentStyle>)
  // and alined with the starting column of the comment
  // specification.
  // Tab substitution is specified by <@dd> where "dd" is a valid
  // positive integer. Blanks will be inserted into the output stream
  // if necessary to position the next character of output at the
  // column indicated by "dd".
  // Conditional substitution is specified by puting a question mark,
  // "?", in column one of the template line.  The line will not be
  // output at all unless at least one valid, non-blank,  symbol
  // substitution  occurs on the line.
  void somtOutputComment(in string comment);
  // Inserts a comment into the output stream.  <comment> must be a
  // string containing the comment with lines in the comment
  // seperated by newlines.
  // The style of output is controlled by <somtCommentStyle>
  void somtOutputSection(in string sectionName);
  // Just like <somto> above, except <sectionName> must be a symbol
  // whose value will be used as the template.
  void somtAddSectionDefinitions(in string defString);
  // <defString> must be a string of the form:
  // :section1
  // value 1 line 1
  // value 1 line 2
  // :section2
  // value 2 line 1
  // :section3
  // value 3 line 1
  // Where the lines that contain a ":" in column 1 immediately followed
  // by a single name are used to intro the start of a new section.
  // The section is named by the name on the colon line.  A backslash
  // can be used to escape a colon in column one that is not supposed
  // to start a new section.
  // Adds the indicated section definitions to this template.
  void somtReadSectionDefinitions(inout FILE fp);
  // Reads section definitions from the indicated file.  The section
  // definitions must be in the form defined above in
  // <somtAddSectionDefinitions>.
  string somtExpandSymbol(in string s, 
                         in string buf);

  // section could have other sections in it then you should call this
