/*
 Driver routine for generating hypertext instrumented code
 from a tree of Fortran source. Hypertext instrumentation allows
 symbols (subroutine names, variable names etc... )
 to be selected in a browser. When a symbol is selected 
 a table showing the definition of that symbol and all
 its occurences within the full code tree appears.
 For each occurence synopsis information, for example
 the line number the file name and the source text of the 
 line referred to is shown.
 This table is also hypertext. By selecting entries in the
 table, for example the line number or the file name or 
 a variable in the source text line that is reproduced
 other elements of the hypertext can be brought up.
 A mechanism for displaying attributes related to symbols
 is also includeed. Attributes describe what class or
 classes a symbol belongs to, for example is the symbol
 a function name, an input parameter, a compile time
 operator etc... Summary tables are also generated
 for viewing the output by attribute.
 A mechanism for linking to an external document, such
 as a text manual, is also included.
