##
# RDoc is a Ruby documentation system which contains RDoc::RDoc for generating
# documentation, RDoc::RI for interactive documentation and RDoc::Markup for
# text markup.
#
# RDoc::RDoc produces documentation for Ruby source files.  It works similarly
# to JavaDoc, parsing the source and extracting the definition for classes,
# modules, methods, includes and requires.  It associates these with optional
# documentation contained in an immediately preceding comment block then
# renders the result using an output formatter.
#
# RDoc::Markup that converts plain text into various output formats.  The
# markup library is used to interpret the comment blocks that RDoc uses to
# document methods, classes, and so on.
#
# RDoc::RI implements the +ri+ command-line tool which displays on-line
# documentation for ruby classes, methods, etc.  +ri+ features several output
# formats and an interactive mode (<tt>ri -i</tt>).  See <tt>ri --help</tt>
# for further details.
#
# == Roadmap
#
# * If you want to use RDoc to create documentation for your Ruby source files,
#   see RDoc::Markup and refer to <tt>rdoc --help</tt> for command line
#   usage.
# * If you want to write documentation for Ruby files see RDoc::Parser::Ruby
# * If you want to write documentation for extensions written in C see
#   RDoc::Parser::C
# * If you want to generate documentation using <tt>rake</tt> see RDoc::Task.
# * If you want to drive RDoc programmatically, see RDoc::RDoc.
# * If you want to use the library to format text blocks into HTML, look at
#   RDoc::Markup.
# * If you want to make an RDoc plugin such as a generator or directive
#   handler see RDoc::RDoc.
# * If you want to write your own output generator see RDoc::Generator.
#
# == Summary
#
# Once installed, you can create documentation using the +rdoc+ command
#
#   % rdoc [options] [names...]
#
# For an up-to-date option summary, type
#
#   % rdoc --help
#
# A typical use might be to generate documentation for a package of Ruby
# source (such as RDoc itself).
#
#   % rdoc
#
# This command generates documentation for all the Ruby and C source
# files in and below the current directory.  These will be stored in a
# documentation tree starting in the subdirectory +doc+.
#
# You can make this slightly more useful for your readers by having the
# index page contain the documentation for the primary file.  In our
# case, we could type
#
#   % rdoc --main README.txt
#
# You'll find information on the various formatting tricks you can use
# in comment blocks in the documentation this generates.
#
# RDoc uses file extensions to determine how to process each file.  File names
# ending +.rb+ and +.rbw+ are assumed to be Ruby source.  Files
# ending +.c+ are parsed as C files.  All other files are assumed to
# contain just Markup-style markup (with or without leading '#' comment
# markers).  If directory names are passed to RDoc, they are scanned
# recursively for C and Ruby source files only.
#
# == Other stuff
#
# RDoc is currently being maintained by Eric Hodel <drbrain@segment7.net>.
#
# Dave Thomas <dave@pragmaticprogrammer.com> is the original author of RDoc.
#
# == Credits
#
# * The Ruby parser in rdoc/parse.rb is based heavily on the outstanding
#   work of Keiju ISHITSUKA of Nippon Rational Inc, who produced the Ruby
#   parser for irb and the rtags package.
