# 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+.
#
# opdir
# |
# |___ files
# | |__ per file summaries
# |
# |___ classes
# |__ per class/module descriptions
#
# HTML is generated using the Template class.
