# We're responsible for generating all the HTML files
# from the object tree defined in code_objects.rb. We
# generate:
#
# [files]   an html file for each input file given. These
#           input files appear as objects of class
#           TopLevel
#
# [classes] an html file for each class or module encountered.
#           These classes are not grouped by file: if a file
#           contains four classes, we'll generate an html
#           file for the file itself, and four html files 
#           for the individual classes. 
#
# [indices] we generate three indices for files, classes,
#           and methods. These are displayed in a browser
#           like window with three index panes across the
#           top and the selected description below
#
# Method descriptions appear in whatever entity (file, class,
# or module) that contains them.
#
# We generate files in a structure below a specified subdirectory,
# normally +doc+.
