Hi,

== Abstract

Langhelp creates an index of documents of various programming languages
and shell commands.
Languages enables you to search documents instantly in Emacs.
If you are a programmer, then you may sometimes wonder, what is the
usage of this function?
If you use Unices, then you may wonder, what is the usage of this
command?
Langhelp answers the question INSTANTLY.

Currently langhelp supports languages and commands below.
  html, svn, bison, cvs, libtool,
  latex, ratpoisonrc, gengetopt, wget, lua,
  guile, php, texinfo, c++, c,
  standards, grep, gdb, diff, octave,
  gauche, python, flex, tcl, m4,
  sed, screenrc, gzip, perl, emacs-lisp,
  ruby, autoconf, hurd, el4r, binutils,
  awk, graphviz-dot, makefile, sh,

Langhelp may be the first tool written in EmacsRuby in the world.
In other words, langhelp is an practical example of EmacsRuby script.

== Environment

Langhelp depends on some tools.
* ((<Ruby 1.8.2 or upper|URL:http://www.ruby-lang.org/>))
* emacs21 / xemacs21
* ((<el4r 1.0.0 or
upper|URL:http://www.rubyist.net/~rubikitch/computer/el4r/>))

I use Debian GNU/Linux and Emacs21.
Langhelp probably works on other GNU/Linux or Unices.
Langhelp also works on Windows(Meadow + Cygwin).

Langhelp does not compete against other document-lookup tools, but
langhelp INTEGRATES document-lookup tools.
The more you have tools, the more usefule langhelp is.


=== Langhelp support tools
The following tools are not mandatory but strengthens langhelp.

: various Info documents
  Langhelp treats Info documents VERY EASY.
: ((<w3m|URL:http://w3m.sourceforge.net/>)),
((<emacs_w3m|URL:http://emacs-w3m.namazu.org/>))
  W3m processes HTML documents.
  Emacs-w3m is a WWW browser in Emacs, uses w3m internally.

  This tool speeds up `ri' calls.
